Abstract

The invention provides a safety control method, device and system based on motor torque. The method includes the steps that according to the vehicle speed, the steering wheel angle, the steering wheelangle change rate and the power generating torque capacity, intervention torque is calculated; according to the vehicle speed, an accelerator pedal signal, a brake pedal signal and the power generating torque capacity, drive requirement torque is calculated; according to the vehicle speed, the steering wheel angle and the steering wheel angle change rate, the working condition is recognized, wherein the working condition comprises a non-dangerous working condition and a dangerous working condition; and if the working condition is the dangerous working condition, a vehicle system is controlledto enter in an active intervention mode, target intervention torque is calculated according to the intervention torque and the drive requirement torque, and a vehicle is controlled according to the target intervention torque. The problems that in the prior art, vehicle active safety torque control is difficult to design and implement from the angle of a power system, and cost is high are solved.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a motor torque-based safety control method, device and system. Background technique [0002] Car driving safety is an important goal of car design, but because the electrification degree of various parts of traditional cars is not very high, the overall torque response speed and precision of the traditional power system composed of fuel engine and gearbox are not high, from the perspective of power system Designing and implementing vehicle active safety torque control is difficult and costly. Contents of the invention [0003] Based on the above problems, the present invention proposes a safety control method, device and system based on motor torque, which solves the technical problem of difficulty and high cost in the prior art to design and implement vehicle active safety torque control from the perspective of power system. [0004] The present invention proposes a safety control ...
