Methods and systems for activating electric vehicles are provided. One method includes, in response to a first command to activate the vehicle, transitioning the vehicle from an inactive state to a wake state where a controller of the vehicle is activated and the vehicle is prevented from being propelled by an electric motor of the vehicle. The method also includes, in response to receiving a second command to activate the vehicle after receiving the first command, transitioning the vehicle from the wake state to a ready state where the vehicle is permitted to be propelled by the electric motor.

A drive unit includes an electric motor, a torque converter, a power transmission unit, a first shaft, a second shaft, and a first switching mechanism. The torque converter amplifies torque from the electric motor in a first rotation direction. The power transmission unit includes first and second forward drive gear trains. The first shaft transmits torque from the electric motor to the torque converter. The second shaft transmits torque from the torque converter to the second forward drive gear train. The first switching mechanism transmits torque from the first shaft to the first forward drive gear train in a first forward drive state. The first switching mechanism does not transmit torque from the first shaft to the first forward drive gear train in a first neutral state. The first switching mechanism is configured not to allow the first forward drive gear train to rotate in a locking state.

A system and method for controlling switching of an electric vehicle to four-wheel drive are provided. The system includes a first motor connected to main drive wheels and configured to output a first torque, a second motor connected to subsidiary drive wheels and configured to output a second torque, a disconnector mounted on an axle shaft for the subsidiary drive wheels, a driver requested torque detector configured to detect a driver requested torque, and a controller configured to release a set output limit of the first motor for a designated time and simultaneously release a set output limit of the second motor when the driver requested torque is greater than or equal to a reference requested torque, and control the first motor to output a maximum torque exceeding the set output limit to the main drive wheels until the disconnector is engaged.

The first switching mechanism is configured not to allow the first forward drive gear train to rotate in a locking state.

Systems and methods for coordinating steering controls between towing vehicles and towed vehicles provide more cohesive parking experiences during towing events, including bidirectional charging towing events. The towed vehicle may be controlled to provide assistive parking steering maneuvers to assist the towing vehicle when parking during the towing event. The assistive parking steering maneuver may include maneuvering a drive wheel of the towed vehicle either toward or away from a detected curb or detected traffic, for example.

A regenerative braking control apparatus of a vehicle may include: a drive motor; a battery for providing driving voltage to the drive motor; a data detector for detecting a driving state information of the vehicle; and a vehicle controller generating a total braking amount based on the driving state information. In particular, the vehicle controller generates a regenerative braking possible amount by using a generatable power of the drive motor and a chargeable power of the battery, performs a regenerative braking when the regenerative braking possible amount is greater than the total braking amount, and also prepares a hydraulic pressure braking based on the regenerative braking possible amount and a regenerative braking amount based on the regenerative braking.

A vehicle power supply system includes a first drive motor, a second drive motor, a first power line to which a first inverter and a first battery are connected, a second power line to which a second inverter and a second battery are connected, a voltage converter that convert a voltage between the power lines, and a charging and discharging control device that controls charging and discharging of the batteries and by operating the inverters and and the voltage converter. A vehicle is able to travel in a drive mode of any of an all-wheel drive mode and a two-wheel drive mode. The charging and discharging control device drives the first drive motor with power that is discharged from the first battery in a case where the drive mode is the two-wheel drive mode.

A charging system, wherein a movable body has an automatic operation function, the charging system comprises: a movable body managing unit that manages a charging state of the storage battery of the movable body; and a waiting space managing unit that manages a usage state of a plurality of waiting spaces for keeping the movable body waiting, the waiting space managing unit has: a waiting space determining unit that determines, among the plurality of waiting spaces that the waiting space managing unit is managing, a waiting space for keeping the movable body waiting after charging of the movable body has completed, if the movable body managing unit has detected that: (i) charging of the movable body is being started; (ii) charging of the movable body has been started; (iii) charging of the movable body is completing; or (iv) charging of the movable body has completed.

A method for remote start control of a hydrogen fuel cell vehicle includes receiving a remote start command via a wireless communication network, transmitting a start signal corresponding to the remote start command through an in-vehicle network, transmitting a start mode in response to the start signal, determining a response waiting time corresponding to the start mode, receiving an operation result of the start signal through the in-vehicle network during the response waiting time, and transmitting the operation result over the wireless communication network.

The electric vehicle of the present disclosure is configured to use an electric motor as a power unit for traveling. The electric vehicle includes an accelerator pedal, a sequential shifter, and a controller. The controller is configured to change a motor torque output by the electric motor in response to operation of the accelerator pedal and operation of the sequential shifter. The controller is configured to change a change rate of the motor torque at least twice during a preset shift time in response to the operation of the sequential shifter.
