A redundant electronic control system includes a control unit, a first output component, and a second output component. The control unit may generate a first execution signal and a second execution signal. The control unit controls the first output component to output the first execution signal to a first actuator, and controls the second output component to output the second execution signal to a second actuator. When the first output component fails, the control unit may control the second output component to output the first execution signal to the first actuator. When the second output component fails, the control unit may control the first output component to output the second execution signal to the second actuator.

VEHICLE MONITORING STRATEGY FOR DETECTING UNINTENDED ACCELERATION DURING SPEED CONTROL

A method detects unintended acceleration of a motor vehicle during a closed-loop speed control mode by determining external forces on the vehicle via a controller, and then calculating a desired acceleration using a measured vehicle speed and the external forces. The method includes determining an actual acceleration of the vehicle, including filtering a speed signal as a first actual acceleration value and/or measuring a second actual acceleration value using an inertial measurement unit (IMU). During the speed control mode, the method includes calculating an acceleration delta value as a difference between the desired acceleration and the actual acceleration, and then using the acceleration delta value to detect the unintended acceleration during the speed control mode. A powertrain system for the motor vehicle, e.g., an electric vehicle, includes the controller and one or more torque generating devices coupled to road wheels of the vehicle.
