enum dwCANVehicleData

A set of enumeration constants representing the default data signals.

The signals can be remapped to actual string based signal representation, but for sanity and to be able to let SDK modules query predefined signals, these defintions are provided here.

Note

There are two angles: steering wheel and steering angle. In general, there is a mapping between the angle of the steering wheel and the actual steering radius of the car. The rule of thumb for some car manufacturers is that the angle of the steering wheel has to be divided by 16 to get an approximation of the actual steering angle. In general, however, that is a non-linear mapping reflecting the current status of the whole car steering geometry.

Enumerator
DW_CAN_STEERING_ANGLE	rad - steering angle of the car. ( neg -> right, pos -> left)
DW_CAN_STEERING_WHEEL_ANGLE	rad - angle of the steering wheel. ( neg -> right, pos -> left)
DW_CAN_STEERING_RATE	rad/s - rotation speed of the steering wheel
DW_CAN_YAW_RATE	rad/s - rate of the yaw rotation of the car
DW_CAN_CAR_SPEED	m/s - speed of the car
DW_CAN_WHEEL_SPEED_0	m/s - speed of the wheel 0
DW_CAN_WHEEL_SPEED_1	m/s - speed of the wheel 1
DW_CAN_WHEEL_SPEED_2	m/s - speed of the wheel 2
DW_CAN_WHEEL_SPEED_3	m/s - speed of the wheel 3
DW_CAN_LONG_ACCEL	m/ss - acceleration along the car axis
DW_CAN_LAT_ACCEL	m/ss - acceleration perpendicular to car axis
DW_CAN_Z_ACCEL	m/ss - acceleration along the z-axis (height)
DW_CAN_X_ACCEL
DW_CAN_Y_ACCEL
DW_CAN_NOT_DEFINED	undefined or unknown type
