[移动开发]Car开发之信号调试文档

文件配置：
1.配置carservice

1. Download attachment: android.hardware.automotive.vehicle@2.0-service
2. Input Shell Command: adb root
3. Input Shell Command: adb remount
4. Input Shell Command: adb push android.hardware.automotive.vehicle@2.0-service /vendor/bin/hw/
5. Input Shell Command: adb reboot
   New Vehicle Properties should take effect and ready for use after emlautor reboot

2.配置json脚本

1. 将脚本car_adp_test.json导入adb push json file to /data/local/tmp/
2. adb shell setenforce 0
   然后执行脚本调试命令：
   lshal debug android.hardware.automotive.vehicle@2.0::IVehicle --set 0x21e00666 -i 2 -s /data/local/tmp/car_adp_test.json

如果需要单个调试，配置完第一步后，执行，

1. adb root
2. adb remount
3. adb shell setenforce 0
4. lshal debug android.hardware.automotive.vehicle@2.0::IVehicle --set -i
   id如下：
   const val Vehicle_Camera_LRCF1_ID = 0x2140A200
   const val Vehicle_Camera_FVCM_ID = 0x2140A201
   const val Vehicle_Camera_RVCM2_ID = 0x2140A202
   const val Vehicle_Camera_LTCM_ID = 0x2140A203
   const val Vehicle_Camera_RTCM_ID = 0x2140A204
   const val Vehicle_Sensor_LRRF_ID = 0x2140A205
   const val Vehicle_Sensor_MRRFL_ID = 0x2140A206
   const val Vehicle_Sensor_MRRFR_ID = 0x2140A207
   const val Vehicle_Sensor_MRRRL_ID = 0x2140A208
   const val Vehicle_Sensor_MRRRR_ID = 0x2140A209

车辆行驶状态id:

const val VEHICLE_GEAR_SELECTION = 289408000//car parking or driving

camera value对应如下
0 => UNKNOWN
1 => WORKING
2 => PROBLEMATIC_DIRTY
3 => PROBLEMATIC_FAULTY
车辆行驶状态如下
2 R档
1 N
4 D
8 P

比如修改Vehicle_Camera_LRCF1_ID的sensor状态为working状态:
lshal debug android.hardware.automotive.vehicle@2.0::IVehicle –set 0x2140A200 –i 2
修改汽车行驶状态为P档:
lshal debug android.hardware.automotive.vehicle@2.0::IVehicle –set 289408000 –i 8

ps：
当然我这是在31即android12上的CarService环境，如果是30的话push进去会开不了机一直报错。
