An assembled battery that secures a heat-dissipation characteristic and has a uniform thickness (size) of unit cells that constitute the assembled battery in a direction of arrangement is provided. In an assembled battery in which a plurality of unit cells are arranged in an arrangement direction, in a unit cell container of at least one of the plurality of unit cells, one or more gap-filling members that fill in a gap between an electrode body and two side walls of the cell container are inserted, and the one or more gap-filling members are disposed so that a distance between the electrode body and a channel-side side wall that directly faces a channel through which a cooling medium passes is shorter than a distance between the electrode body and a non-channel-side side wall that does not directly face the channel.

An apparatus for supplying power for a vehicle includes a first battery, a second battery, a switching device, a monitoring device and a control device. The first battery is electrically connected to load devices which are mounted on the vehicle. The second battery serves as a backup power source. The switching device switches the first and second batteries. The monitoring device monitors remaining capacity for each of the first and second batteries. When the control device determines that the remaining capacity of the second battery is less than the remaining capacity of the first battery based on information monitored by the monitoring device, the control device controls the switching device so as to conduct switching of the first and second batteries.

A worm gear for a vehicle steering system. The worm gear includes a tooth worm and a tooth worm wheel which mesh with each other. The teeth on the worm wheel are shaped such that the pressure angle of the left tooth flank and the right tooth flank are different from each other so that the normal force between the worm and the worm wheel is independent of the direction of rotation of the torque exerted on the worm by the worm wheel.

Disclosed herein are an electronic brake system and a control method thereof. The electronic brake system includes a master cylinder connected to a reservoir storing oil, including a master chamber and a master piston provided at the master chamber, and configured to discharge the oil according to pedal effort of a brake pedal, a sensor configured to measure a displacement of the brake pedal, a pedal simulator configured to provide a reaction force according to pedal effort of the brake pedal and including a simulator chamber connected to the master cylinder to accommodate the oil, a hydraulic actuator provided between the master cylinder and a wheel cylinder and configured to control a hydraulic pressure flow delivered to the wheel cylinder, a first hydraulic pressure supply device operated by an electrical signal which is output by corresponding to the displacement of the brake pedal, and configured to supply a hydraulic pressure to the hydraulic actuator, and a second hydraulic pressure supply device provided between the reservoir and the master cylinder and configured to provide a vibration pedal feel to the brake pedal.

The invention discloses a middle-position calibrating method for an electric power-assisted steering tube column. The middle-position calibrating method comprises the following steps: S1, detecting whether the whole vehicle state, including tire pressure values of tires, and toe-in values of front wheels, meet requirements or not before starting an engine, and besides, detecting whether a handwheel, a steering mechanism and a steering wheel are positioned at the middle position of the whole vehicle; S2, if middle-position calibration is not performed on the electric power-assisted steering tube column, or the middle-position calibration for the electric power-assisted steering tube column is not finished, executing S3, wherein an indication module continuously flashes for indication; S3, comparing standard middle-position information with middle-position calibration information of the electric power-assisted steering tube column, which is detected in real time, if the middle-position calibration information of the electric power-assisted steering tube column, which is detected in real time, is not matched with the standard middle-position information, performing middle-position calibration correcting operation; and S4, if the electric power-assisted steering tube column does not need to continue middle-position calibration, indicating that the middle-position calibration of the electric power-assisted steering tube column is correct by the indication module. The middle-position calibrating method disclosed by the invention is convenient and easy to operate.

The power generation controller includes a control command receiving section receiving a control command transmitted from an external control unit for controlling an internal combustion engine, a control command holding section holding the control command received by the control command receiving section, and an excitation current control section controlling an excitation current of a generator driven by the internal combustion engine on the basis of the control command held by the control command holding section. The excitation current control section is configured to control the excitation current on the basis of a control command transmitted from the external control unit when the internal combustion engine is in a stopped sate.

A system and method for providing multiple commands to an ignition coil driver circuit to provide spark, ion signal integration, and ignition coil shunting during a cycle of a cylinder is presented. In one example, multiple voltage pulses are provided over a single conductor communication link. The voltage pulses provide encoded instructions for ignition timing, ignition coil shunting, and ion signal integration.
