Abstract

The invention provides a driving and braking parameter automatic calibration method, which comprises the steps of: outputting a driving / braking control sequence according to a preset time interval before a vehicle enters automatic driving, wherein the driving / braking control sequence comprises a plurality of pieces of torque data; acquiring acceleration information and speed information corresponding to each piece of the torque data; performing two-bit interpolation processing according to each piece of the torque data and the acceleration information and the speed information corresponding tothe torque data, and generating a torque characteristic table; acquiring current acceleration information and current speed information of the vehicle when the vehicle performs automatic driving; anddetermining the current torque data through looking up the torque characteristic table according to the current acceleration information and the current speed information of the vehicle. Therefore, the labor and time costs are saved, the calibration operation is simple and convenient, and the calibration personnel can start to operate the device easily.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to an automatic calibration method and device for driving and braking parameters. Background technique [0002] The control of unmanned vehicles can be divided into lateral control and longitudinal control. The lateral control mainly controls the steering wheel angle to stably track the target path, and the longitudinal control controls the speed of the vehicle by controlling the accelerator and brake. However, it is often impossible to obtain important information on the real-time engine and transmission, such as the MAP map of engine speed, crankshaft output torque, and throttle opening, etc., so the controller design based on longitudinal dynamics modeling of unmanned vehicles becomes extremely difficult . In this case, it is important to test the driving and braking parameters of the driverless vehicle. [0003] At present, to test the driving and braking parameters of...
