Step S304: the vehicle-mounted device performs standardized calibration on the target seat according to the diagnosis information of the target seat.
Specifically, in the process of the target seat standardization calibration, the vehicle-mounted device can prompt a user in a voice manner, the seat can move in the process, no person or article is needed in the range, and the standardization process is affected. Here we take the driver's seat as an example, and perform standardized calibration. The whole seat standardization process is divided into a plurality of items, and front-back range standardization, upper-lower range standardization and backrest range standardization are sequentially carried out, and all the items need to be executed.
Specifically, as shown in fig. 6, S304 may include the following steps:
Step S3041: the in-vehicle apparatus performs standardized calibration of a first range for a target seat, the first range being a boundary of a front-rear distance of the target seat.
Specifically, the first range may be, for example, (50, 20), where 50 represents the adjustment distance of 50cm for the forwardmost end of the seat relative to the starting position of the seat, and 20 represents the adjustment distance of 20cm for the rearwardmost end of the seat relative to the starting position of the seat.
Step S3042: the in-vehicle apparatus performs standardized calibration of a second range for the target seat, the second range being a boundary of an up-down distance of the target seat.
In particular, the second range may be (30, 20), for example, where 30 represents a maximum distance of 30cm for an upward adjustment of the height of the seat relative to the seat starting position and 20 represents a maximum distance of 20cm for a downward adjustment of the height of the seat relative to the seat starting position.
Step S3043: the in-vehicle apparatus performs standardized calibration of a third range for the target seat, the third range being a boundary of a reclining angle of the target seat.
In particular, the third range may be, for example, (90 °,110 °), wherein 90 ° represents a minimum adjustment angle of 90 ° and a maximum adjustment angle of 110 ° of the seat relative to the seat cushion
The normalization of the front-rear range and the upper-lower range is mainly distance range adjustment, and the backrest is mainly angle range for adjusting and rotating the backrest. Taking the adjustment of the front-rear range of the seat as an example, the vehicle-mounted device circularly sends an execution command of seat forward movement to the ECU of the seat system, such as 0x2f0401, the ECU of the seat system receives the command, then starts a motor of the seat to forward the seat, and sends a read command of the front-rear position of the seat after each forward movement command is sent to acquire the front-rear position information of the seat, such as 0x22080a, the ECU of the seat system returns to 0x62080a32, wherein 0x32 is the position replaced by decimal and is 50, the position at the moment is recorded, when the position data does not change any more after the circular movement, the vehicle-mounted device sends a position record command to the ECU of the seat system, and the current position is stored in the ECU of the seat system to serve as the boundary of the front range.
After the current position is recorded, the vehicle-mounted device circularly sends an execution command of seat backward to the driver seat system, for example, the vehicle-mounted device sends an execution command 0x2f0402 to the ECU system of the driver seat system, after the ECU of the driver seat system receives the command, the motor of the driver seat is started to backward move the seat, after each backward movement command is sent, a front-back position reading command is sent to the driver seat to acquire front-back position information of the driver seat, if the position data of the driver seat does not change any more, the driver seat is indicated to be moved to the rearmost end, at the moment, a position recording command is sent to the ECU of the driver seat system, the current position is stored in the ECU of the driver seat system as a boundary of a rear end range, for example, 0x31080b is sent, after the ECU of the driver seat system receives the command, the information is automatically stored, after the current rear end position is normalized, the front-back range is indicated to be normalized successfully, and then the upper-lower range and the backrest range of the driver seat are normalized according to the same method.
The embodiment of the application also provides a method for standardized calibration of the electronic seat of the vehicle. As shown in fig. 7, the method may include the following steps:
s701: the vehicle-mounted device acquires target vehicle type information of a vehicle connected with the vehicle-mounted device.
Specifically, S701 corresponds to S301, and will not be described here.
S702: the vehicle-mounted device acquires target seat information of the target vehicle type.
Specifically, S702 is identical to S302, and will not be described here again.
S703: the vehicle-mounted device searches for diagnosis information of a target seat corresponding to the target vehicle model from the stored diagnosis protocols.
Specifically, S703 corresponds to S303, and will not be described here.
S704: the in-vehicle apparatus transmits an activation command to an electronic control unit ECU of a target seat system of the target vehicle type.
S705: the in-vehicle apparatus receives an activation command returned from the target seat system ECU.
S706: and if the vehicle-mounted equipment determines that the target seat is activated according to the activation command, the vehicle-mounted equipment acquires first fault code information of the ECU of the target seat system.
S707: and if the vehicle-mounted equipment determines that the target seat system ECU is faulty according to the first fault code information, the vehicle-mounted equipment sends a command for clearing the fault to the target seat system ECU.
S708: if the vehicle-mounted equipment determines that the target seat system ECU has no fault according to the first fault code information, the vehicle-mounted equipment performs standardized calibration on the target seat of the target vehicle type according to the diagnosis information of the target seat of the target vehicle type.
After activation of the target seat and before standardized calibration, first failure information needs to be sent to the ECU of the target seat system to detect whether the hardware device of the target seat is failed, ensuring that the target seat system is able to operate normally before the target seat is standardized.
In another possible embodiment, after S304, as shown in fig. 8, the method for calibrating the electronic seat of the vehicle according to the standardization may further include:
step S305: the in-vehicle device transmits a command of the second trouble code to the vehicle.
Step S306: and the vehicle-mounted equipment receives the second fault code information replied by the vehicle.
After the standardized calibration of the driver seat, the vehicle device sends a command to read the second fault code to the ECU of the driver seat system to obtain whether the seat has a fault in the standardized initialization process, for example, 0x190208 is sent, and the ECU of the driver seat system returns to 0x5902089000 to indicate that there is a fault 9000. If the second fault code information read indicates that a fault is generated, a command for clearing the fault code is sent to the ECU of the driver seat system, for example, the vehicle-mounted equipment sends a command 0x14ff00 for clearing the fault code to the ECU of the driver seat system, after clearing is completed, a command for reading the fault code is sent again, if the fault still exists, the fault is generated, the standardized calibration is failed, and the vehicle owner is required to execute the standardized calibration operation of the driver seat again. If no fault code is generated or the fault code can be cleared, the voice prompts the user that the standardization of the driver seat is completed, and the user can test whether the adjustment of the power seat is normal or not through a button of the driver seat. When it is confirmed that the standardized calibration of the driver seat is successful, if the present function is to be stopped, the user may pull the in-vehicle apparatus off or press an on/off button of the in-vehicle apparatus to stop the program.
