Abstract

The invention discloses an accelerator control system and method in a man-machine co-driving mode of an automobile and belongs to the technical field of automobile manufacturing. The system is characterized in that a signal input end of an accelerator central control unit of the system is respectively and correspondingly connected with a signal output end of an accelerator pedal sensor, a signal output end of an automatic driving controller and a signal output end of a man-machine co-driving mode switch, a signal output end of the accelerator central control unit is correspondingly connected with a signal input end of an engine control unit, a signal output end of the engine control unit is correspondingly connected with a signal input end of a gearbox control unit and a signal input end of a fuel injector electromagnetic valve, and a signal output end of the gearbox control unit is connected with a gearbox through a driving unit. The system is advantaged in that problems that in an automatic driving mode of a vehicle with both manual driving and automatic driving, due to the fact that a gearbox clutch cannot be engaged, an engine idles, and the vehicle cannot run can be solved.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an accelerator control system and a control method in an automobile man-machine co-driving mode. Background technique [0002] Existing automobile accelerator control system comprises the accelerator pedal sensor that is located on the automobile accelerator pedal, and its signal output end is connected with the signal input end of the engine control unit, and the signal output end of the engine control unit is connected with the signal of the gearbox control unit. The input terminals are connected; when the driver steps on the accelerator pedal, the accelerator pedal sensor generates an accelerator pedal signal to the engine control unit, and the engine control unit converts it into an accelerator opening signal, and controls the injector solenoid valve according to the accelerator opening signal , and then control the fuel injection volume of the accelerator, s...
