A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing includes a single external power access for the shift actuator. A controller interprets a shaft displacement angle, determines if the transmission is in an imminent zero or zero torque region, and performs a transmission operation in response to the transmission in the imminent zero or zero torque region.

A vehicle control device includes a controller configured to control operation of a braking device and operation of a driving motor. The controller can switch between a normal mode of controlling acceleration/deceleration in accordance with a driver's acceleration/deceleration operation, and a cruise control mode of maintaining the vehicle speed at a target speed without being dependent on the acceleration/deceleration operation. The controller is configured to execute braking control, including braking by the braking device and regenerative braking by the driving motor, during the cruise control mode in accordance with a change in a vehicle traveling condition. The braking control includes causing the braking device to generate a braking force without using the regenerative braking and subsequently executing a braking-force switching process including increasing a braking force by the regenerative braking while reducing the braking force from the braking device, if a determination result indicates that the vehicle speed is stable.

A hybrid vehicle includes an engine that drives first wheel, and a motor that drives second wheel. The hybrid vehicle includes (1) a minute speed launch support mode where the hybrid vehicle is driven only by the motor as a drive source, (2) a sudden launch support mode where the hybrid vehicle is driven by the engine and motor as the drive source, and (3) a smooth launch support mode where the hybrid vehicle is driven only by the motor as the drive source in an early stage, is driven by the engine and motor in a middle stage, and is driven only by the engine in a late stage, and if an operation amount of an acceleration instruction unit is not 0 or is substantially not 0, any one of the support modes is executed according to an operation status of the acceleration instruction unit.

In accordance with an exemplary embodiment, a vehicle is provided that includes a body, a drive system, and a control system for controlling the adaptive cruise control functionality for the vehicle. The drive system is disposed within the body, and has adaptive cruise control functionality. The control system includes: one or more sensors disposed onboard the vehicle and configured to obtain sensor data for monitoring a driver of the vehicle while the vehicle is stopped during adaptive cruise control operation while a target vehicle in front of the vehicle has stopped; and a processor coupled to the one or more sensors and configured to provide instructions for automatically resuming movement of the vehicle, when the target vehicle resumes movement, based on the monitoring of the driver of the vehicle.

Methods and systems for improving operation of a vehicle driveline that includes an engine and an automatic transmission with a torque converter are presented. In one non-limiting example, the engine may be stopped while a vehicle in which the engine operates is rolling. A transmission coupled to the engine may be shifted as the vehicle rolls so that vehicle response may be improved if a driver requests an increase of engine torque.

A control device for performing start assist control for an internal combustion engine includes: a first start assist processing unit that executes a first start assist process that brings a first engagement device into slip engagement at a first engagement pressure while increasing a torque generated by a rotating electrical machine; and a second start assist processing unit that increases, when the first start assist process fails to start the internal combustion engine, an engagement pressure of the first engagement device to a second engagement pressure higher than the first engagement pressure while increasing the torque generated by the rotating electrical machine. The second start assist processing unit determines the second engagement pressure on the basis of a rotational speed of the internal combustion engine in the first start assist process.

A control system for an electric vehicle configured to simulate an engine stall which might occur in conventional vehicles while preventing the simulation of the engine stall in an unfavorable situation. A controller of the control system is configured to: execute an engine stall control to simulate a behavior of the conventional vehicle in a situation where an engine stall occurs by stopping a motor, when a virtual engine speed calculated by a virtual engine speed calculator falls below a predetermined speed; and execute a hold assist control to apply a brake torque to the wheel by the brake device upon execution of the engine stall control.

A vehicle for activating launch control in response to establishment of a predetermined activation condition includes an electric power conversion device configured to control electric power supplied to an electric motor, the electric motor configured to drive a driven wheel according to electric power supplied via the electric power conversion device, a temperature control circuit in which a temperature control medium circulates to control a temperature of the electric power conversion device, and a control device. The temperature control circuit includes a pump configured to pump the temperature control medium. The control device is configured to control the pump, and when the activation condition is established, the control device is configured to control the pump such that a flow rate of the pump is high as compared with a case where the activation condition is not established.

A method for operating a drive-train of a vehicle, such as a municipal or agricultural utility vehicle, having at least one drive machine, a vehicle transmission with at least two gears, at least one drive axle and at least one auxiliary power take-off. The method includes controlling or regulating a supply of normal power from the drive machine as a function of a normal torque characteristic. Depending on the operating situation, supplying additional power to the at least one drive axle and/or to the at least one auxiliary power take-off. The supplied additional power is controlled or regulated as a function of operating situation dependent torque characteristics which are called up as a function of the selected gear at the time.

Provided is an acceleration suppression apparatus having improved practicality. The acceleration suppression apparatus includes: an in-vehicle sensor (20) configured to acquire information relating to a position of an own vehicle and information relating to an operation of an operating element of the own vehicle to output the acquired information; and a parking assist ECU (10) configured to execute, based on the information acquired from the in-vehicle sensor (20), acceleration suppression control for suppressing acceleration of the own vehicle by controlling at least one of a drive device (30) or a braking device (40) mounted on the own vehicle. The parking assist ECU (10) is configured to execute the acceleration suppression control when, in a situation in which the own vehicle is positioned in a predetermined region including a parking space, a traveling mode of the own vehicle matches a predetermined mode defined in advance as a traveling mode when the own vehicle is being parked in the parking space.
