A vehicle includes an electric machine, an engine, an engine mount, and a controller. The engine has a base speed that corresponds to a speed of the electric machine and an engine power demand. The engine mount is disposed between the engine and a vehicle structure such as a frame or unibody. The controller is configured to, in response to compression of the engine mount, increase an engine speed to a value that is greater than the base speed to reduce engine lugging.

Hybrid vehicle and method of reducing engine lugging

A hybrid electric vehicle (HEV) and methods for operation having a powertrain that includes an engine, an electric machine and storage battery, and a transmission coupled via a drive shaft to wheels having regenerative-friction brakes. The HEV and transmission incorporate regenerative and adaptive braking and a capability to detect nearby obstacles and other vehicles. Such controllers monitor and report the nearby-vehicle distance and a brake pedal tip-lift time and position. In response, the controller(s) cause the electric machine to generate electric power with negative torque, which decelerates the transmission and wheels at a constant or variable rate, adjusted so the nearby-vehicle distance during deceleration equals or exceeds a predetermined, lead-lag distance to nearby vehicles or obstacles. An adaptive cruise signal may also be generated that may indicate driver vehicle preferred settings and profiles, and constant, adjustable, learned, and driver selectable deceleration profiles, which are utilized to control deceleration during braking.

Regenerative braking system and method

A vehicle may include a transmission having an electric machine, an engine, and a controller. The engine may be selectively coupled with the transmission via a disconnect clutch. The controller may be programmed to, in response to an anticipated engine start request, command a disconnect clutch pre-stroke to couple the engine to the transmission prior to an actual engine start request while operating the vehicle in electric mode.
