Reversing radar system

 

 

1. Outline

 

(1) structure summary

 

The reversing radar system consists of a sensor, a control module and an alarm device. The reversing radar system is based on the principle of ultrasonic distance measurement and computer data blur processing technology to determine whether there are obstacles in the reversing direction of the car, and to indicate the distance of the nearest obstacle. When the operating gear is hung in the reverse gear, the reverse switch is turned on, and the reverse light is on. After the controller receives the reverse signal, the ultrasonic sensor is controlled to send an ultrasonic signal, and the principle of the sensor self-receiving and multiple-receiving is used to accurately and completely return the echo signal. Passed to the controller, after analysis and processing by the controller, it is determined that there is an obstacle in the detection distance and the distance of the nearest obstacle, and the buzzer in the combination meter is controlled to issue an alarm sound, and different frequencies are emitted according to different distance ranges. The tweet reminds the distance of the obstacle and achieves the security warning function.

Reversing camera system

1. Outline

 

(1) structure summary

The reversing image system mainly consists of a rearview camera and an MP5 main unit. The camera is powered by the IGN signal. When the R-range signal is detected through the CAN bus node, the system starts immediately. At the same time, the steering wheel angle signal is obtained through the CAN bus node and the rear of the vehicle is obtained. The real-time image is sent to the camera for trajectory path calculation and image superposition processing. Finally, the image information superimposed with the reverse trajectory is transmitted to the vehicle display to assist the driver in reversing the vehicle.

Tire pressure monitoring

 

 

1. Outline

 

(1) structure summary

 

Tire pressure monitoring system can monitor the pressure and temperature in the tire, give alarm in time when the setting value is exceeded (the alarm indicator is indicated by the instrument light), help the driver to grasp the condition of the tire in real time and reduce the traffic accidents caused by the tire failure, increasing vehicle driving safety.

 

TPMS system consists of three components: alarm indicator (integrated in the dashboard), tire pressure monitoring controller, tire pressure monitoring sensor.Detailed composition is as follows

 

Spare parts name	Quantity	Remark
Tire pressure monitoring controller	1	Install under the secondary instrument panel.
Tire pressure monitoring controller	4	Installed in four tires
alarm indicator	2	Integrated on the instrument cluster (two indicators) 1, tire pressure alarm indicator. 2, TPMS alarm indicator.

 

Alarm indicator

 

 

Symbol (instrument)	Indicator lamp type	Indicator type
	Tire pressure abnormal	Rapid Leakage: Flashing Low Pressure: Steady High Pressure: Steady High Temperature: Steady
	System fault	Sensor battery low battery: Always on Sensor failure: Steady light High frequency acceptance failure: Steady light Communication between controller and instrument disconnected: Steady light

 

Alarm type and description

 

Alarm type	Description
Quick tire leak	When the system is running, one or more tire pressure drops more than 30kPa within 1 minute and a rapid leak alarm is issued; if the pressure does not change or rises, the rapid leak alarm is released.
Low pressure	Under system operating conditions, one or more tire pressures are lower than the manufacturer's specified cold pressure value 75% (165kpa), issued a low pressure alarm; pressure returned to normal, lifting the low pressure alarm.
High pressure	Under system operating conditions, one or more tire pressures are higher than the manufacturer's specified cold pressure value 125% (275kpa), a high pressure alarm is issued; the pressure returns to normal and the low pressure alarm is released.
High temperature	When the system is running, one or more tire temperatures are higher than 85 °C and a high temperature alarm is issued; the temperature returns to normal and the high temperature alarm is released.
Sensor battery low power	When the system is running, one or more of the tire pressure sensors have a battery level lower than a certain value and a low-power alarm is issued. When the power is restored to normal, the low battery alarm is released.
Sensor failure	When the system is running, one or two sensor valid data is not received within 5-10 minutes (the rest of the sensors can receive valid data), and a sensor failure alarm is issued; all sensor valid data are received and the failure alarm is released.
High-frequency acceptance failure	In the system running state, the receiving controller does not receive any sensor data for 20 consecutive minutes and sends a high frequency to accept the failure alarm; any sensor valid data is received and the failure alarm is released.

 

1. Ignition switch ON/START. If four sensors are bound, the tire pressure warning indicator will turn off after 2s.

2. Ignition switch ON/START. If four sensors are not connected, the TPMS lamp will flash after the tire pressure warning indicator point and TPMS indicator light turn on 2s and then go out.

3. Enter the sensor learning mode. Both indicators will light up at the same time (lit). After the binding is successful, both indicators will be off at the same time.

4. During running, the system and pressure are normal and the two indicators do not light up.

5. The alarm is released and the corresponding alarm indicator goes out.

6. The system is divided into three levels according to the priority of the alarm situation (the highest level);

       Level 1: Fast Leakage

Level 2: Low pressure, high pressure, and high temperature Three levels: Sensor battery low power,

Sensor failure, high frequency acceptance failure

When an alarm status is indicated, the high-level alarm indicator lights first, and both LEDs do not light at the same time.                                                                                                                                                                                                       

 

After an alarm occurs (the corresponding indicator light), if the ignition switch is turned off and then back on, the system clear various alarm status indication, re-test.

(4) maintenance precautions

 

The TPMS system is the tire pressure monitoring auxiliary system. The signal transmission is completed by the high-frequency signal. When the high-frequency signal is interfered by the same frequency electromagnetic field and interfered with for a long time, it will send a system fault alarm. When the car is away from the strong magnetic field, alarm status will be automatically lifted, it is normal

Driving on a bumpy road, the vehicle turns, and the tires are stressed differently. As a result, the tire pressure is too high or too low during this period. Sometimes the system may occasionally get an alarm and travels to a flat and straight road. If the pressure is normal, it will be automatically released alarm, it is normal.

After a long time of parking, the tire pressure is normal and there is no obvious change. No sensor data has been received for 20 consecutive minutes. The TPMS lamp is on. After the vehicle is running, the sensor starts transmitting data and the TPMS lamp point goes out. This is normal.

 

(2). the fault diagnosis

 

(1) Troubleshooting Table

 

Number	faults phenomena	Cause Analysis	Solutions
1	The ignition switch is ON, the tire pressure warning indicator and the TPMS indicator light up at the same time and will not turn off after 2s.	The original receiver of the vehicle is not learning binding.	To the 4S shop, professionals are required to use hand-held learning tools to reacquire all tire sensor IDs and bind the receiver controller.
		The acceptance controller has been replaced and the receiving controller has not been learned to bind.
2	Tire pressure warning light flashes	During the driving process, tires were damaged by punctures, splits, etc., and the tire pressure rapidly decreased.	You must stop as soon as possible to check all tires and air pressure.
		While parking (ignition switch ON/START), deflate the tire.	After the air release is stopped or inflated, the alarm will be automatically released.
3	Tire Pressure Alarm Indicator	During stop (ignition switch ON/START), the tire is deflated, causing the air pressure to be too low.	Inflate the tire to the correct air pressure (tire pressure is listed on the tire pressure label).
		During parking (ignition switch ON/START), the tire is inflated and the air pressure is too high.	Deflate the tire to the correct pressure value.
		When driving on bumpy roads/turning vehicles, the tires are subjected to different forces, causing the tire pressure to be too high or too low during this period.	Drive to a flat/straight road surface and if the pressure is normal, the alarm will be automatically canceled.
		Insufficient tire pressure was detected during driving (the tire was not inflated for a long time / leaked due to tire damage).	You must stop as soon as possible to check all tires and air pressure.
		You must stop as soon as possible to check all tires and air pressure. The vehicle travels at high speed and overload, causing tires to overheat.	Slow down and do not overload.
		During running, the air pressure is insufficient and the friction increases, causing the tire to overheat.	You must stop as soon as possible to check all tires and air pressure.

 

Serial No.	faults phenomena	Cause Analysis	Solutions
4	TPMS indicator lamp normally on	One or more tire pressure sensors have battery levels below a certain value.	Return the sensor to the 4S shop in time and re-learn the binding.	See Tire Pressure Monitoring System TPMS indicator lamp normally on
		One of the four tires does not have a tire pressure sensor installed in one or both tires.	Install the correct sensor in the 4S shop and relearn the binding.
		One or two of the four tires are mounted incorrectly (ie, the sensor ID does not match the receiving controller ID).	Install the correct tire in the 4S shop and relearn the binding.
		Of the four tires, the tire pressure sensor of one or two of the tires fails and data cannot be transmitted.	Change the sensor to the 4S shop and relearn the binding.
		The high-frequency receiving module of the receiving controller is damaged and has not received any sensor data for 20 consecutive minutes.	Check the receiving controller at the 4S shop. If you need to replace the receiving controller, you must re-learn the binding.
		The sensor IDs of all four tires and the receiving controller ID do not match and no valid sensor data was received for 20 consecutive minutes.	Re-learn the bindings at the 4S shop.
		When the vehicle is stopped for a long time, the tire pressure is normal and there is no obvious change. The sensor does not send data to the receiving controller, and no sensor data is received for 20 consecutive minutes.	It is a normal phenomenon. After the vehicle is running, the sensor starts transmitting data and the alarm state is automatically released.
		In the same frequency interference area (strong interference, continuous) traffic, such as airports, radio towers, etc., may cover the sensor signal.	After leaving the same frequency interference area, the alarm status will be automatically released.
		Receiver controller wire harness bad contact	Unplug the receiving controller and reconnect it
5	Ignition switch from OFF to ON, tire pressure alarm indicator does not light	Indicator light failure	To the 4S shop, ask a professional to check the meter. If the meter is damaged, the meter needs to be replaced.	See Wheel Tire Pressure Unsatisfactory Tire Pressure Alarm Indicator Light Off

Maintenance Spectial Precautions

 

Precautions:

Do not reset the EMS, PEPS at the same time, otherwise, the key will not be used and the module will need to be replaced

When the ICM indicates that the vehicle can also be started "N" times, after the fault problem is locked, the diagnostic instrument is used to perform the process of resetting the number of starts. (If the vehicle requires power-on check, you can directly execute the PEPS reset start times. At this time, you can solve the start-up problem, but be sure to find out the cause of the decrease in the number of start-ups. If you do not find out the reason for the delivery, the car will still have this problem again. .)
