摘要： A control system for a hybrid vehicle. The system comprises a controller configured to cause a net negative drive torque to be applied by an engine or an electric machine of the vehicle to the input shaft of a transmission in a direction opposing travel of the vehicle to effect braking, determine when a transmission gear shift is about to occur requiring a non-negative torque to be applied at the input shaft, and when the gear shift is about to occur, temporarily cause a net non-negative drive torque to be applied to the input shaft by causing the electric machine to apply a positive drive torque to the input shaft to compensate for negative torque applied by the engine, and cause brake force to be applied by a braking system to compensate for a reduction in negative drive torque applied to the input shaft, while the gear shift occurs.

摘要： A controller for a motor vehicle powertrain, the controller being configured to control the amount of torque generated by each of a plurality of drive torque sources, each drive torque source being coupled via a respective torque transfer arrangement to a respective group of one or more wheels, the controller being configured to cause a first of the drive torque sources, during acceleration, deceleration and substantially constant speed operation, substantially continually to apply a drive torque to a first group of one or more wheels to which the first drive torque source is coupled acting in a first direction relative to a longitudinal axis of the vehicle and causes a second of the drive torque sources, during acceleration, deceleration and substantially constant speed operation, substantially continually to apply a drive torque to a second group of one or more wheels to which the second drive torque source is coupled, the direction of drive torque applied to the second group being in a second direction opposite the first such that a net drive torque applied to the first and second group in combination corresponds substantially to a predetermined drive torque demand value, the predetermined torque demand value being determined at least in part by reference to a torque demand signal received by the controller.

摘要： A hybrid electric vehicle is capable of direct drive by internal combustion engine, electric motor, or both. In order to provide a consistent overrun response, a torque controller determines an appropriate deceleration characteristic according to, for example, transmission speed ratio, vehicle gradient and vehicle mass, and commands the electric motor and the engine to contribute a negative torque which meets the required deceleration characteristic. A ‘tip’ function modifies the characteristic in the event of a change commanded by the vehicle driver, for example a change of speed ratio.

摘要： Embodiments of the invention relate to a motor vehicle controller operable automatically to stop and subsequently to restart an engine of a vehicle according to a prescribed control methodology. The controller is operable automatically to adjust an engine stop delay parameter in dependence on the value of at least one vehicle endurance parameter. The engine stop delay parameter corresponds to a period for which the engine of the vehicle remains switched on when it is determined that a condition exists allowing the engine to be switched off during the course of a drive cycle. The value of the endurance parameter is responsive to stop/start operations being performed during the course of a drive cycle. The controller is operable to adjust the engine stop delay parameter to prevent the value of the endurance parameter exceeding a prescribed maximum endurance value before a prescribed time period elapses.
