摘要： A method for learning engine clutch kiss point of a hybrid vehicle is provided. The method includes adjusting a speed of a driving motor to be reduced when a deceleration event is generated in front of the hybrid vehicle and adjusting a speed of an engine to be synchronized with the speed of the driving motor. An engine clutch that connects the engine with the driving motor or disconnects the engine from the driving motor is engaged to start and then a kiss point of the engine clutch is learned by detecting the kiss point that is generated when the engine clutch is in a slip state.

摘要： A vehicle includes an engine and at least one controller. In response to a change in a rate of change of a driver control input to the vehicle, the at least one controller is programmed to alter conditions under which the engine will be started and stopped such that engine-on time increases due to the rate increasing and decreases due to the rate decreasing.

摘要： A powertrain assembly has multiple torque actuators. The assembly includes a first controller configured to control a first torque actuator and a second controller configured to control a second torque actuator. The first controller is configured to receive a signal from an input sensor and convert the signal into a torque demand. The second controller is configured to receive the torque demand from the first controller and determine respective optimal torque allocations for the first and second torque actuators based on the torque demand and a plurality of optimization factors. The first controller includes a processor and tangible, non-transitory memory on which is recorded instructions for executing a method of controlling the multiple torque actuators across the at least two controllers via a dynamic look-up table. The dynamic look-up table is populated by a plurality of stored torque production allocation values based on a respective plurality of torque requests.

摘要： A vehicle includes an engine, a climate control system, a cabin, and a controller. The controller is programmed to, in response to the climate control system supplying heat to a vehicle cabin and receiving a request for an economy mode, decrease an engine coolant temperature engine start threshold. The controller is further programmed to, in response to the engine coolant temperature becoming less than the threshold, start the engine.

摘要： A vehicle control system for reducing shocks resulting from restarting an engine under EV running mode. The vehicle control system is applied to a vehicle including an engagement device that selectively connect the engine with the powertrain, and a motor adapted to generate a drive force and connected with the powertrain. In the vehicle, a first mode is selected to propel the vehicle by the motor while interrupting the torque transmission between the engine and the powertrain and stopping the engine, and a second mode is selected to propel the vehicle by the motor while allowing the torque transmission between the engine and the powertrain and stopping the engine. The vehicle control system selects the second mode if a control response of at least any of the engagement device and the motor is estimated to be out of a predetermine range when the vehicle is running while stopping the engine.
