A method controls a mode of a vehicle in a connected car service terminal and is driven by at least one processor. Driver exit information for determining a driver getting out for the vehicle is collected and whether the driver has left the vehicle based on the driver edit information is checked. A driver exit notification signal informing that the driver has left the vehicle is transmitted to a connected car service server and a valet mode in an inactivated state is activated upon receiving a valet mode activation signal of the vehicle from the connected car service server.

An active purge system (APS) according to a driving state of a hybrid vehicle includes an active purge unit (APU) configured to pressurize a vaporized gas generated in a fuel tank of the hybrid vehicle and supply the pressurized vaporized gas to an intake pipe, and a control unit configured to control the APU, where the control unit gradually controls a processing amount of the vaporized gas according to the driving state of the hybrid vehicle. The processing amount of the vaporized gas is gradually controlled using the APS according to the driving state of the hybrid vehicle, particularly, a number of places at which slip occurs in a power transmission system of the hybrid vehicle so that degradation of driving ability due to the occurrence of slip is reduced.

A system and method for controlling a hybrid electric vehicle using a driving tendency are provided. The method includes determining a driving tendency level based on data to determine a driving tendency of a driver and determining a target engine torque using an engine torque map based on a vehicle speed and a required torque. Whether the driving tendency level corresponds to a predetermined level is determined as well as whether the required torque is equal to or greater than a torque that corresponds to an optimal operating point of an engine when the driving tendency level corresponds to the predetermined level. The target engine torque is then adjusted when the required torque is equal to or greater than the torque that corresponds to the optimal operating point of the engine.

A vehicle drive device includes a first drive unit that drives first wheels; a second drive unit that drives second wheels; and a control device. When the state of charge of an electrical storage device is less than a first threshold value and a vehicle speed is less than a second threshold value, the control device performs control such that when the vehicle speed is greater than or equal to zero and required drive power is greater than or equal to zero, the operating mode of the first drive unit is set to a second mode to output the required drive power from the second drive unit, and when the vehicle speed is greater than zero and the required drive power is less than zero, the operating mode of the first drive unit is set to a first mode so the first drive power source can generate electric power.

A vehicle controller includes processing circuitry and a storage device. The storage device stores relationship specifying data that specifies a relationship between a vehicle state and an action variable. The processing circuitry is configured to execute an obtaining process obtaining the vehicle state, an operating process operating an electronic device based on a value of the action variable, a reward calculation process assigning a reward based on the vehicle state, an updating process updating the relationship specifying data using the vehicle state, the value of the action variable, and the reward as inputs to an update mapping. When a value of the action variable designated by the relationship specifying data is a first value, a process in which the operating process operates the electronic device in accordance with the first value is executable in a first situation and is not executable in a second situation.

The transmission control unit includes a gear ratio abnormality determination unit and a limp home control unit. The gear ratio abnormality determination unit is configured to determine that a gear ratio is abnormal when, during travelling at a predetermined gear position, a difference between an actual gear ratio, which is calculated based on a transmission input shaft rotation speed and a transmission output shaft rotation speed, and a set gear ratio at the predetermined gear position is equal to or greater than a set value. The limp home control unit is configured to, when the gear ratio abnormality determination unit determines that the gear ratio is abnormal, output a disengagement instruction for disengaging all of the plurality of friction elements, when it is confirmed that a neutral state is shifted to according to the output of the disengagement instruction, determine engagement/disengagement of a specific friction element among the plurality of friction elements based on rotation/stop information of a rotation member of the stepped transmission mechanism, and determine an evacuation gear position based on determination information on the engagement/disengagement of the specific friction element, and shift the gear position to the determined evacuation gear position.

An apparatus and method for controlling a power train of a vehicle may include an external information detection device detecting information on an external environment of the vehicle; an internal information detection device detecting information on a driving state of the vehicle; and a control device detecting occurrence of an overtaking situation of the vehicle according to the information on the external environment and the driving state, and controlling the power train of the vehicle based on a rotation angle of a steering wheel of the vehicle so that a response speed to a manipulation of an accelerator pedal in the vehicle speeds up when the occurrence of the overtaking situation of the vehicle is detected.

A display device for a vehicle includes: an image display unit configured to display a direction indicating image that indicates a travel direction of the vehicle; and a control device configured to execute travel control of the vehicle. The direction indicating image is switchable between a first image that indicates a first travel direction of the vehicle and a second image that indicates a second travel direction of the vehicle, the second travel direction being opposite to the first travel direction. In a case where the control device switches the travel direction of the vehicle from the first travel direction to the second travel direction, the image display unit switches the direction indicating image from the first image to the second image based on a vehicle speed of the vehicle, a state of a power transmission device, and a steering state of the vehicle.

A braking control arrangement is for a braking system of a vehicle. The braking system comprises an anti-lock braking system, ABS, and an electronic stability control, ESC. The braking control arrangement comprises a module that is arranged to operate with the anti-lock braking system and the electric stability control. The arrangement is also arranged to drive a gear arrangement of the vehicle in such a way that when braking the vehicle, the anti-lock braking system works, and a slippery road is detected, the gear arrangement of the vehicle is driven to shift a reverse gear.

A vehicle includes a controller configured to switch between a constant speed traveling mode in which a vehicle speed is held constant and an inertial traveling mode in which a prime mover is stopped or in an idling state, and a clutch apparatus configured to connect and disconnect power transmission between the prime mover and an output target, and the controller controls the clutch apparatus and decreases a clutch capacity so as to transit to the inertial traveling mode when detected that the vehicle is traveling on a downhill road during the constant speed traveling mode, and the controller controls the clutch apparatus and increases the clutch capacity so as to transit to the constant speed traveling mode when detected that the vehicle traveling on the downhill road has terminated.
