Abstract

The invention discloses a speed adjustment device and particularly discloses a self-adapting acceleration and deceleration device. The self-adapting acceleration and deceleration device comprises a steering wheel turning angle sensor, a steering wheel turning speed sensor, a steering wheel acceleration sensor, a vehicle speed sensor, a DSP (Digital Signal Processing) chip and a master controller, wherein the steering wheel turning angle sensor, the steering wheel turning speed sensor and the steering wheel acceleration sensor are mounted on a steering wheel steering tube shaft, and the vehicle speed sensor, the DSP chip and the master controller are mounted in a drive axle housing. According to the self-adapting acceleration and deceleration device, the influence on the actual traveling speed of a vehicle caused by the turning speed, turning angle and acceleration of a steering wheel is taken into full account, an engine is controlled to be in accelerated operation when the vehicle is speeding, and the engine is controlled to be in decelerated operation when the speed of the vehicle is lower than an ideal speed, so that the self-adapting vehicle speed acceleration and deceleration are realized.

Description

technical field [0001] The invention discloses a speed regulating device, especially an adaptive acceleration and deceleration device. Background technique [0002] When a car accelerates or decelerates while turning, its actual driving speed is related to the steering wheel speed and steering acceleration. When measuring the vehicle speed in the prior art, the influence of the steering wheel rotation speed, rotation angle, and acceleration on the actual driving speed of the vehicle is ignored, so there is an error in the measured vehicle speed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an adaptive acceleration and deceleration device for the above-mentioned deficiency of the background technology. [0004] The present invention adopts following technical scheme for realizing above-mentioned purpose of the invention: [0005] The adaptive acceleration and deceleration device includes a steering whe...
