摘要： A control system includes a throttle control module, an exhaust gas recirculation (EGR) control module, and a diagnostic control module. The throttle control module selectively maintains a desired throttle area when a vehicle is in a coastdown mode. The EGR control module opens an EGR valve when the desired throttle area is maintained. The diagnostic control module selectively diagnoses an error of an EGR system based on a pressure increase measured in an intake manifold of the vehicle when the EGR valve is open.

摘要： An engine control system for a vehicle comprises a torque module and a drag request evaluation module. The torque module controls torque output of an engine based on a driver torque request and increases the torque output based on a wheel drag torque request generated based on a driven wheel speed. The drag request evaluation module disables the increase of the torque output when the driven wheel speed is greater than an undriven wheel speed by more than a predetermined speed.
