Vehicle control method and system

Abstract

The invention discloses a vehicle control method and system, and relates to the field of vehicle control information processing, the system comprises a general control circuit board, a general controlchip, a sensor and a plurality of driving circuits are arranged on the general control circuit board, and the general control circuit board is physically and directly connected with an actuator through the driving circuits; the general control circuit board is used for directly receiving and analyzing state information fed back by an actuator, monitoring information acquired by a sensor and personnel operation information; the general control chip generates a control command set according to the state information, the monitoring information and the personnel operation information; and the general control circuit board is also used for directly driving the corresponding actuator through the corresponding types of driving circuits according to the control command set. The general control circuit board and various driving circuits of actuators corresponding to various functional modules are integrated into one device, layout and wiring of the whole vehicle can be simplified, the development difficulty of the whole vehicle is reduced, the transportability is high, the development cost is low, and the development period is shortened.

Description

technical field [0001] The invention relates to the field of vehicle control information processing, in particular to a vehicle control method and system. Background technique [0002] At present, the control units on the car are independent of each other. They are connected and communicated through the vehicle wiring harness, and the control of the whole vehicle is completed through the cooperation between the controllers. At the same time, a single control only controls a certain aspect of the function; for example The engine controller mainly controls the work of the engine, while the steering controller mainly controls the work of the steering gear. [0003] In the case of multiple control units, different control units will have different suppliers, so there will be the following problems: For example, in the pre-development stage of the vehicle, it will involve supplier designation, supplier technical exchanges, and the relationship between the control units.

Problems solved by technology

[0003] In the case of multiple control units, different control units will have different suppliers, so there will be the following problems: For example, in the pre-development stage of the vehicle, it will involve supplier designation, supplier technical exchanges, and the relationship between the control units. Functional interaction and signal interaction are cumbersome, and it takes a long time and a large cost of manpower and material resources to adjust before it can provide the interaction of each control unit in the function control of the vehicle and the interaction of signals between each control unit

Furthermore, due to the functional correlation between different control units, interconnection is required, which eventually leads to difficulties in the spatial layout of wiring harnesses and control units.

[0004] The number of control units on a vehicle ranges from a dozen to as many as 20 to 30. In this case, the cost of development is high, quality control is difficult, and system security risks are relatively high
