The invention discloses an adaptive cruise control method and system for a new energy automobile, and the method comprises the steps: enabling an ADC to transmit a request torque of adaptive cruise control to a VCU for acceleration control, and transmitting a function state of the ADC; the VCU responds to the request torque sent by the ADC and sends the whole vehicle high-voltage power-on state, the whole vehicle controller function state, the door takeover state flag bit information, the accelerator opening degree and the driving gear to the ADC; for deceleration control, the ADC calculates a required deceleration and sends the required deceleration to the IPB, the ADC calculates a required braking force based on the required deceleration, distributes the required braking force between electric braking and hydraulic braking and sends a braking feedback required torque to the VCU, and the VCU sends a feedback torque limit value to the IPB. According to the new energy automobile self-adaptive cruise control method, the self-adaptive cruise control function is achieved through interaction among the ADC, the IPB and the VCU.

    本发明公开了一种新能源汽车自适应巡航控制方法及系统,所述方法包括:对于加速控制,ADC向VCU发送自适应巡航控制的请求扭矩,同时发送ADC的功能状态;VCU对ADC发送的请求扭矩进行响应,并向ADC发送整车高压上电状态、整车控制器功能状态、门接管状态标志位信息、油门开度和行驶档位;对于减速控制,ADC计算需求减速度,并将需求减速度发送到IPB,ADC基于需求减速度计算需求制动力,并将需求制动力在电制动和液制动之间分配,并将制动回馈需求扭矩发送到VCU,VCU向IPB发送回馈扭矩限值。本发明的新能源汽车自适应巡航控制方法,通过ADC、IPB、VCU三者间的交互实现自适应巡航控制功能。
