摘要： A secondary controller for controlling the performance of a moving automobile is described. The secondary controller can be configured to communicate with one or more vehicle controllers, such as the engine control unit, while the automobile is being driven. The secondary controller can send control commands, such as self-test or diagnostic commands to the vehicle controller to effect the operation of the vehicle's power train. The secondary controller can receive power train related data from the engine control unit and based upon the received power train data determine when to send the control commands. In one embodiment, the secondary controller communicates with the vehicle controller via the vehicle's diagnostic port, such as an OBD-II port. In another embodiment, the secondary controller can be configured to control a variable displacement engine in a vehicle to improve the fuel efficiency of the vehicle while it is driven.

摘要翻译： 描述了用于控制移动汽车的性能的二次控制器。 二次控制器可以被配置为在汽车被驱动时与一个或多个车辆控制器（例如发动机控制单元）通信。 二级控制器可以向车辆控制器发送诸如自检或诊断命令的控制命令，以实现车辆动力传动系的操作。 次级控制器可以从发动机控制单元接收动力传动系相关数据，并且基于所接收的动力传动系数据确定何时发送控制命令。 在一个实施例中，次级控制器经由车辆诊断端口（例如OBD-II端口）与车辆控制器通信。 在另一个实施例中，二级控制器可被配置成控制车辆中的可变排量发动机，以在车辆被驱动时提高车辆的燃料效率。
