Abstract: A vehicle system includes an engine, a transmission, a differential, and a waste heat recovery (WHR) drive that converts thermal energy into mechanical and electrical energy. The WHR drive can include a WHR power unit structured to convert thermal energy into rotation of a WHR drive shaft. A motor/generator having a motor/generator shaft can selectively operate as a motor or a generator. A mechanical linkage is structured to selectively link an output shaft to one of the WHR drive shaft and the motor/generator drive shaft independently of the other of the WHR drive shaft and the motor/generator drive shaft. The output shaft is selectively coupled to one of the engine, the transmission, or the differential. The vehicle system may also include a traction motor to provide drive to the vehicle. The output shaft can be selectively coupled to the traction motor or the engine.

Abstract: A waste heat recovery (WHR) hybrid power system can be utilized in vehicles to convert heat energy into mechanical energy. The WHR system can include a WHR power unit structured to convert thermal energy into rotation of a WHR drive shaft. A motor/generator having a motor/generator shaft can selectively operate as a motor or a generator. A mechanical linkage can be structured to selectively link a output shaft to one of the WHR drive shaft and the motor/generator drive shaft independently of the other of the WHR drive shaft and the motor/generator drive shaft.

CPC classification number: B60W30/17
Abstract: A vehicle system, apparatus, and/or method is provided. The vehicle system includes a powertrain including a prime mover and a transmission, and an electronic control system in operative communication with the powertrain including an adaptive cruise control (ACC) controller. The electronic control system is configured to determine a speed profile for a vehicle-in-front of the vehicle system while operating the vehicle system along a route. In response to the speed profile for the vehicle-in-front, the electronic control system is further configured to modify one or more output parameters of the powertrain to control one or more of a vehicle speed, a vehicle acceleration, and a vehicle deceleration of the vehicle system to inhibit control of the one or more output parameters by the ACC controller.
