A vehicle includes a power storage unit, a regenerative generator, and an electronic control unit. The regenerative generator is connected to the power storage unit and is configured to perform regenerative power generation. The electronic control unit is configured to perform regeneration amount enlargement control in which positions of stopping and deceleration of the vehicle by input of driver's operations are predicted or set based on route information, regenerative power generation by the regenerative generator is controlled, and a regeneration power amount charged into the power storage unit is enlarged. The electronic control unit is configured to restrict the regeneration amount enlargement control when executing a predetermined vehicle speed adjustment mode by comparison with when the predetermined vehicle speed adjustment mode is not selected, the vehicle running with automatic adjustment of vehicle speed in the predetermined vehicle speed adjustment mode selected by intentional input from the driver.

A drive power control apparatus for a vehicle includes a controller that adjusts the drive power for driving a vehicle to compensate for a parameter that affects the running state of the vehicle. When the vehicle enters a region where the acceleration of the vehicle needs to be changed based on the running environment or when the vehicle is traveling in the region in which the acceleration of the vehicle needs to be changed based on the running environment, the controller makes the amount by which the drive power is adjusted less than the amount by which the drive power is adjusted when the vehicle is traveling in a region other than the region in which the acceleration of the vehicle needs to be changed based on the running environment.

A target pathway generating device is provided with a map information acquisition unit, a curved path determination unit, an obstacle determination unit and a target pathway generating unit. The map information acquisition unit acquires map information. The curved path determination unit determines whether or not a curved path is present on a driving pathway of a vehicle based on the map information. Upon determining that a curved path is present, the obstacle determination unit determines whether or not there is an object to be avoided in the vicinity of the curved path. Upon determining that there is an object to be avoided, the target path generating unit generates a target pathway of the vehicle in order to avoid a predetermined region including the object to be avoided.

A driving support system according to the present invention is provided with an actuator for steering steered wheels of a vehicle and is used for supporting driving of the vehicle by making use of steering by means of the actuator. The driving support system has an image taking device for taking a forward image ahead the vehicle, a determiner for determining a controlled variable of the actuator on the basis of the forward image acquired by the image taking device, a limiter for limiting the controlled variable when a time change of the controlled variable of the actuator determined by the determiner is off a predetermined range, and a controller for controlling the actuator. The limiter sets a limit value for limiting the time change of the controlled variable of the actuator so that the limit value at a start (or at an end) of the driving support control is different from the limit value in continuation of the driving support control. In this configuration, the limit value to prevent a driver from sensing discomfort is set at the start (or at the end) of the driving support control, while the limit value suitable for the driving support control is set during continuous execution of the driving support control. This permits the system to achieve suppression of the discomfort at the start (or at the end) of the support control and improvement in performance of the support control in continuation of the control together.

There is provided an electro-optical apparatus which is wearable on a human body, including: a display unit that includes pixels and a drive circuit which drives the pixel; and an case that contains the display unit and includes a contact surface which comes into contact with the human body. The contact surface is arranged to have at least one space from the display unit.

A speed change control device for an automatic transmission according to this invention determines whether or not a request to downshift a gear position of the transmission exists during traveling in a manual speed change mode (S1, S2), and calculates an input shaft rotation speed of the transmission following a downshift based on the downshift request (S4). When it is determined that the calculated rotation speed is higher than a rotation speed limit value (S5), the speed change control device performs a downshift to a gear position at which the input shaft rotation speed of the transmission is lower than the calculated rotation speed (S6, S8).

A control system for a hybrid vehicle configured to reduce frequency of establishing an engine braking force is provided. The control system is configured to operate a first motor as a motor to increase torque of an output member while halting the output shaft of the engine by a brake, and to increase the deceleration torque of the second motor, if a state of charge of the battery is higher than a predetermined threshold level when deceleration of the hybrid vehicle is demanded.

A moving assist apparatus assists a vehicle which includes an internal combustion engine and an electric motor as a driving source to move from a current position to a destination. The moving assist apparatus includes a planning unit configured to, for each section obtained by dividing a traveling route from the current position to the destination, plan one traveling mode from a mode of not maintaining a charge storage amount of a battery and a HV mode of maintaining the charge storage amount of the battery, based on a traveling load associated with the section. The planning unit is configured to replan the traveling mode under a predetermined condition, and when the predetermined condition is satisfied, when a remaining distance of the section on which the vehicle is traveling is less than a threshold a, to replan a current ‘traveling mode to be the traveling mode in priority.

In a power steering apparatus, a basic-target-rotational-speed setting portion 42 sets a basic target rotational speed Rb of an electric motor 27 on the basis of the vehicle speed and the angular velocity of steering. A temperature-coefficient setting portion 43 sets a temperature coefficient α which becomes smaller with an increase in the temperature. A target-rotational-speed setting portion 44 sets a target rotational speed R of the electric motor 27 on the basis of the formula R=α·Rb. A motor-drive control portion 45 controls a drive circuit 28 so that this target rotational speed R will be attained.
