摘要： A vehicle includes a motor, a resolver which detects a rotation angle of the motor, an automatic transmission which shifts rotation of the motor and transmits the shifted rotation to a drive shaft, and an ECU which performs learning control for correcting an error of the resolver and shift control of the automatic transmission. The ECU controls the automatic transmission such that, when the learning control is performed, a gear ratio becomes higher at a prescribed vehicle speed, than that when the learning control is not performed. By controlling the automatic transmission as described above, even when the vehicle is traveling at a low speed, a rotation speed of the motor easily reaches a rotation speed at and above which the learning control of the resolver can be performed. Accordingly, an opportunity to perform the learning control of the resolver can be obtained early.

摘要： An inverter converts input DC power into AC power and supplies the AC power to a motor generator. An inverter control unit executes shutdown control for stopping power conversion by the inverter, when operation of the motor generator is not requested. A transmission control unit controls the transmission. When a state quantity related to a rotation speed of the motor generator increases to a prescribed quantity during execution of the shutdown control, the inverter control unit continues the shutdown control and the transmission control unit executes shift control for controlling the transmission to reduce the rotation speed of the motor generator.

摘要： In a first slip suppression control by a first slip suppression control unit when a vehicle stops on a slope, an electronic control unit controls an output torque of an electric motor so that a rotation speed of an input rotation member of a hydraulic power transmission reaches a predetermined target rotation speed during stopping of an engine. The electronic control unit starts the engine when the output torque of the electric motor is greater than a predetermined torque. Accordingly, when the output torque of the electric motor at a rotation speed under a slip suppression control is insufficient, the output torque of the engine can be used and thus a locked state of the electric motor is appropriately prevented.

摘要： A server includes a storage device that stores history information indicating a history of a state of a vehicle, and a controller that performs a process using the history information. The controller makes a first determination of whether or not a vehicle load exceeds a first load. For the vehicle for which it has been determined that the vehicle load is higher than the first load in the first determination, the controller makes a second determination of whether or not an environmental load is higher than a second load. When it is determined that the environmental load is higher than the second load in the second determination, the controller outputs an area change request requesting a change of the dispatch area of the vehicle to another dispatch area lower in the environmental load than a current dispatch area.

摘要： 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.
