Abstract

The invention discloses a control method and device for a whole vehicle controller cruise system of an electric automobile, and the method comprises the following steps: reading cruise switching signals of the electric automobile, and judging whether the electric automobile enters into a cruise control mode by using an analog-to-digital conversion module of a microcontroller; reading messages regarding the whole vehicle dynamic information, and connecting a communication module of the microcontroller, subjected to level switch, with a communication interface of the whole vehicle controller to determine a cruise control method; connecting a cruise speed adjusting button with an universal input / output interface of the microcontroller by a filter circuit, and determining a cruise speed set value; connecting brake pedal signals with the analog-to-digital conversion module by a sampling circuit, and determining the brake information of a driver; and connecting accelerator pedal signals with the analog-to-digital conversion module by a sampling circuit, determining the accelerator pedal opening, and setting the cruise speed according to a control policy. By using the control method and device of the whole vehicle controller cruise system of the electric vehicle, the cruise system controlling can be run stably and efficiently, thus providing a hardware platform controlled by the cruise system for the whole vehicle controller, and compensating performance lack of the whole vehicle controller in the field of the cruise system controlling.

Description

technical field

[0001] The invention discloses a control method for a cruise system of a vehicle controller of an electric vehicle, and also provides a device for realizing the method, belonging to the technical field of new energy vehicle control. Background technique

[0002] At present, the vehicle controller of the existing electric vehicle mainly has the following functions: control the power-on and power-off logic of the vehicle, dispatch and manage the motor control system and battery management system, and it is responsible for the collection and processing of vehicle information and the realization of vehicle control strategies, etc. important task. Due to the heavy workload, traditional vehicle controllers often do not have cruise control functions. As a result, the cruise control function of most electric vehicles is missing. Although a small number of electric vehicles have the control function of the cruise system, this function is often integrated on the cont...
