Embodiment Construction

[0035] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0036] The embodiment of the present invention aims at the relative independence of the EPS system and the automobile master control system in the prior art, the electronic controller of the EPS system and the automobile master controller of the automobile master control system have no information communication, resulting in the sensor and the automobile master controller in the EPS system The sensors in the main control system of the car are repeatedly installed and worked repeatedly, resulting in increased costs, heavy workload, and the inability to monitor the working status of the EPS system in real time. To provide a vehicle-mounted electronic control system and an electric vehicle, the EPS The system and the main control system of the automobile are...

Abstract

The invention provides a vehicle-mounted electric control system and an electric vehicle and relates to the technical field of complete vehicle control. The vehicle-mounted electronic control system includes a signal sensing device, an electronic control device and a power torque mechanism, wherein the signal sensing device is linked to the electronic control device via a controller local area network (CAN) bus, and the power torque mechanism is connected to the electronic control device via a hard wire; the electronic control device is used for acquiring demanded power torque according to a signal collected by the signal sensing device and outputting the demand power torque to the power torque mechanism. According to the scheme, the combination of a vehicle main control system and an electric power steering system is achieved, the number of sensors installed on the vehicle is reduced, the cost is saved, the workload of an electronic controller is reduced, and meanwhile the reliabilityof the electronic controller is improved.

Description

technical field [0001] The invention belongs to the technical field of complete vehicle control, and in particular relates to a vehicle-mounted electronic control system and an electric vehicle. Background technique [0002] In the prior art, many automobiles adopt the traditional manual steering mode, that is, the rotation of the steering wheel is manually controlled, and then transmitted to mechanical devices such as the steering shaft of the automobile wheel to realize the steering of the automobile. With the increasing development of automotive electronic technology, the requirements for automotive design and control level are getting higher and higher, especially the energy-saving and environmental protection features of automobiles. At present, many domestic and foreign manufacturers are equipped with electric power steering (Electric Power Steering, referred to as: EPS) system on light commercial vehicles to replace the high energy consumption and high pollution hydra...
