A control method and apparatus of a vehicle including a drive motor are provided. The control apparatus includes a data detector that detects data to operate the vehicle and a controller that determines whether a braking condition is satisfied based on the data. The controller calculates a total braking amount and a regenerative braking allowance when the braking condition is satisfied and determines whether a shifting condition is satisfied when the braking condition is satisfied. A first actuator receives a control signal from the controller to adjust a hydraulic pressure supplied to each frictional element of the transmission and a second actuator receives the control signal from the controller to adjust the hydraulic pressure supplied to the wheel cylinder. An inverter receives the control signal from the controller to determine a switching operation of a switching element.

A vehicle behavior control method is suitable for a vehicle behavior control device. The vehicle behavior control device includes: a lateral acceleration sensor, detecting lateral acceleration occurring in a vehicle body; a wheel speed sensor, detecting a wheel speed of a wheel; a steering angle sensor, detecting a steering angle of the wheel; a steering angle lateral acceleration calculation unit, calculating steering angle lateral acceleration from the wheel speed and the steering angle; and a yaw moment control unit, applying yaw moment to the vehicle body. In the vehicle behavior control method, when the lateral acceleration and the steering angle lateral acceleration meet a predetermined condition, a yaw moment directed inward in a turning direction of the vehicle body is applied by the yaw moment control unit.

An apparatus and system for actuating a manual gearbox, particularly of a motorcycle having a drive engine, and for carrying out a gear change while the clutch is engaged between the drive engine and the manual gearbox. The apparatus has a selector shaft, which can be actuated rotationally, and a gear-selector drum, which can be actuated rotationally. The gear-changing apparatus has a gear-change lever provided for actuating the selector shaft, and is adapted for influencing the output torque of the drive engine. One or more magnetic sensor(s), such as Hall effect sensors, are provided for sensing rotational actuation of the selector shaft and, optionally, for sensing rotational actuation of the gear selector drum. The sensor(s) send a signal to a controller and mechanisms known for affecting a change in gear to a lower or higher gear.

Systems and methods for controlling performance characteristics of a vehicle are provided. A system for controlling performance characteristics of a vehicle includes a memory storage device including at least one torque curve profile stored thereon. The at least one torque curve profile includes a mapping of accessible torque for the vehicle with respect to an engine speed of an engine coupled to the vehicle. The system also includes an electronic control unit operatively coupled to the memory storage device, the electronic control unit configured to re-map the at least one torque curve profile in response to receipt by the electronic control unit of an electronic signal indicating a change in a vehicle condition.

When driver's deceleration intention is detected during traveling by a motor generator with an engine being stopped, a clutch is engaged to start the engine, and thereafter disengaged. When an engine speed after engine start is lower than a reference rotational speed being an input shaft rotational speed produced by driving force reversely transmitted from drive wheels, the engine speed is increased to a target rotational speed lower than the reference rotational speed. When the engine speed reaches the target rotational speed, output from the engine is decreased and the clutch is reengaged. Thus, while engine stall when activating the engine brake, which is due to the engine speed too low after engine start, is avoided by increase in the engine speed, the clutch is reengaged earlier so as to activate the engine brake fully, generating deceleration feeling the driver expects.

Embodiments of the present invention provide a motor vehicle control system for selecting and/or determining a driving surface and for controlling a plurality of vehicle subsystems to operate in a plurality of subsystem control modes in dependence on the selected/determined driving surface, the system being operable in a manual control mode selection condition in which a user is able to select said driving surface and an automatic control mode selection condition in which the system is configured to select said driving surface automatically, wherein the vehicle control system is provided with a memory arranged to memorize a last selected control mode that was selected prior to vehicle de-activation or key-off when operating in the automatic control mode selection condition, and upon the next subsequent vehicle activation or key-on, the system is configured to continue operating in the memorized control mode and to automatically obtain new data in respect of a driving surface over which the vehicle is moving before allowing a change in control mode to take place.

A method of operating an engine of a work machine, via a controller, includes detecting a request for a transmission shift of a transmission of the work machine from a neutral gear to a desired starting gear; determining a current transmission output speed of the transmission; determining a desired transmission output speed of the transmission corresponding to the desired starting gear; determining a desired minimum speed of the engine based on a difference between the current transmission output speed and the desired transmission output speed; and causing, based on the request for the transmission shift, the engine to operate at or above the desired minimum speed prior to a completion of the transmission shift from the neutral gear to the desired starting gear.
