Embodiment 1

[0035] A vehicle control system, comprising a vehicle controller 1 and an engine 2, the vehicle controller 1 is connected to the engine controller 21 on the engine 2 through a CAN bus; the vehicle controller 1 is connected to a clutch switch respectively 4. Gearbox high and low gear switch 5, gearbox half gear switch 6, auxiliary brake switch 7, neutral switch 9, parking brake switch 11, service brake switch 12 and the signal output end of the accelerator pedal sensor 13 are connected; The vehicle controller 1 sends commands to the engine controller 21 to start the engine, shut down the engine, control the engine speed or control the engine torque through the CAN bus.

Embodiment 2

[0037] Embodiment 2 is basically the same as Embodiment 1, and its difference is:

[0038] The vehicle controller 1 is connected to the signal output end of the cruise control switch 8, and when the cruise control switch 8 is turned on, the vehicle controller 1 sends an instruction to drive at a constant speed through the CAN bus to the engine controller 21; The vehicle controller 1 is connected with the control terminals of the gearbox protection solenoid valve 15, the exhaust brake solenoid valve 16, the brake light relay 17 and the electronic fuel pump 18 respectively; connected to the signal output.

Embodiment 3

[0040] Embodiment 3 is basically the same as Embodiment 2, and its difference is:

[0041] The vehicle controller 1 is connected to the signal output end of the air conditioner request switch 10 .

Abstract

A vehicle control system comprises a vehicle controller and an engine. The vehicle controller is connected with an engine controller on the engine through a CAN bus; the vehicle controller is connected with the signal output ends of a clutch switch, a gearbox high-low-gear switch, a gearbox half-gear switch, an auxiliary brake switch, a neutral gear switch, a parking brake switch, a driving brake switch and an accelerator pedal sensor; and the vehicle controller sends instructions of engine starting, engine shut-down, control over the rotating speed of the engine and control over the torque of the engine to the engine controller through the CAN bus. The engine controller becomes an actuator of the vehicle controller, the adaptation requirement of the engine controller is reduced, the design independence of vehicle manufacturers is improved, and the adaptation and development cost is reduced.

Description

technical field [0001] The invention relates to the field of vehicle control, in particular to a vehicle control system, which is particularly suitable for optimizing the control of the vehicle, improving the adaptability of the engine, and reducing the cost of adaptation. Background technique [0002] As the core control component of the entire vehicle power system, the engine controller collects accelerator pedal signals, brake pedal signals, transmission clutch signals, neutral switch signals and other various switch and sensor signals, and after making corresponding judgments, controls each It can work with a variety of peripheral electrical components or send control commands to other power system control units through the CAN bus. With the increasing requirements of automobile power and safety, the application of electronic products in automobiles is also increasing. [0003] Most of the existing engine controllers use international brand suppliers. Since the engine c...
