Abstract

The automatic misoperation preventing control system includes one hydraulic acceleration unit and one hydraulic braking unit. The hydraulic acceleration unit includes one accelerating pedal, one hydraulic control valve, one braking hydraulic sensor, one solenoid valve and one accelerating hydraulic sensor. The accelerating pedal is connected mechanically with the valve core of the hydraulic control valve; the hydraulic control valve has one first output connected to the hydraulic oil tank, one second output connected to the input of the solenoid valve and one third output connected to the braking cylinder inlet of the hydraulic control valve; the solenoid valve has one first output connected to the accelerating hydraulic sensor and one second output connected the hydraulic oil tank; and the braking hydraulic sensor is connected to the braking cylinder inlet of the hydraulic braking unit.

Description

technical field [0001] This invention relates to automotive control systems. Background technique [0002] With the development of my country's automobile industry, automobiles are becoming increasingly popular. In the middle of driving, accidents of personal injury and death caused by misoperation during emergency braking by car drivers occur from time to time. [0003] In the prior art, mechanical structures such as mechanical pedals, gears, and overrunning clutches are used to compensate for the mishandling of the accelerator during emergency braking, so as to achieve safe driving and stable handling. [0004] figure 1 Shown is a vehicle control device in the prior art. It includes an accelerator pedal 1, a pedal rod 3, the pedal rod 3 is fixedly connected to the accelerator shaft 2, and meshing gears 4 and 5 are arranged between the accelerator shaft 2 and another shaft 10, and the other shaft 10 is connected to the connecting block 6 through a clutch 7, and the conne...
