Road load compensation for matching acceleration expectation

Disclosed is a vehicle road load compensation system that includes an accelerator pedal, a throttle, a transmission wherein a vehicle torque is generated proportional to the transmission gear and the motor power, and a control unit disposed within the vehicle and configured to receive real-time sensor data relating to the road load of the vehicle. The control unit includes a real-time throttle map relating the accelerator pedal position to the throttle position, such that a given accelerator pedal position directs a corresponding target throttle position. The control unit also includes a real-time shift map relating a desired transmission gear to a current transmission gear, vehicle speed, and throttle position. In response to the sensor data, the control unit updates the throttle map and shift map such that the vehicle torque is altered based on the road load of the vehicle. The controller may also update a real-time torque converter lockup map.

Method and system for vehicle control

Methods and systems are provided for mitigating reverse vehicle rollback. In one example, in response to a request to shift a transmission from reverse to forward when vehicle speed is elevated, vehicle brakes are applied and the actual transmission shift is delayed until the vehicle motion in the reverse direction is sufficiently decelerated. Additionally, the engine may be stalled and restarted before the transmission shift is performed.

Drive train and operating method for a hybrid vehicle with an overrun-enabled forward gear

The invention relates to a drive train for a hybrid vehicle with an internal combustion engine, with a transmission and with an electric machine, wherein the electric machine is arranged between the internal combustion engine and the transmission. The drive train can be provided in a simple, economical and/or space-saving manner in that the transmission comprises at least one overrun-enabled forward gear transmitting traction torque only and at least one overrun-free forward gear. A hybrid vehicle can be operated with a drive train of this kind easily and efficiently in that, when an overrun-enabled forward gear transmitting only traction torque is engaged and while the vehicle speed lies below a certain engagement speed for an overrun-free forward gear and at least one criterion for the presence of a driving torque is established or satisfied, the transmission is shifted into the overrun-free forward gear.

Control apparatus for hybrid vehicle

A power control ECU controls electric power and engine power of a hybrid vehicle. The power control ECU includes a request driving force calculating portion that calculates a request driving force calculated in accordance with an accelerator operation amount, a travel driving force calculating portion that calculates a travel driving force as a value that belatedly follows the request driving force, and a dashpot control processing portion. The dashpot control processing portion sets a value of the request driving force as a value of a final request driving force used to calculate request engine power when a difference of the request driving force with respect to the travel driving force is less than a predetermined positive value, and sets a value that belatedly follows the request driving force when the difference is greater than or equal to the predetermined positive value.
