Abstract: A charge control device is mounted on a vehicle to which external power for charging a storage battery is supplied from an external power supply. The charge control device has an acquisition part, a calculation part, and an output part. The acquisition part acquires a detection result of a physical quantity sensor that detects a physical quantity related to charging of the storage battery. The calculation part changes a target value of the physical quantity when a charge amount of the storage battery is equal to or greater than a target charge quantity and a difference between the target value of the physical quantity and the detection result is lower than a predetermined value. The output part outputs an instruction signal including an instruction to control an external power based on a target value to the external power supply.

Abstract: A diagnostic device includes: a shutdown command unit that outputs a shutdown command to shut down a power switch with the control of an inverter stopped when a switch diagnostic condition is satisfied in the conduction state of the power switch, an acquisition unit that acquires a voltage change, which is the change in the detected voltage of a voltage sensor in response to the change in the number of revolutions of the motor after the output of the shutdown command by the shutdown command unit, and a diagnostic unit that diagnoses whether the power switch is in an on-failure state based on the voltage change.

Abstract: A motor vehicle comprises a motor configured to input and output power for driving; an inverter configured to drive the motor; a power storage device configured to transmit electric power to and from the motor; a system main relay configured to connect and disconnect the power storage device with and from a power line on an inverter-side; and a control device configured to enable the motor vehicle to be driven with turning on the system main relay according to a predetermined procedure in response to a system on-operation. The motor vehicle does not perform failure diagnosis of the inverter when an abnormality signal of the inverter is generated before a predetermined time after the system main relay is turned on in response to the system on-operation, while performing the failure diagnosis when the abnormality signal of the inverter is generated after the predetermined time.

Abstract: A circuit for demodulating an input signal is described. The circuit may be configured to demodulate signals modulated with amplitude-based modulation schemes, such as amplitude shift keying (ASK). The demodulator may comprise a clock extractor configured to generate a clock signal in response to receiving an amplitude-modulated input signal, a phase shifter configured to generate a sampling signal by phase-shifting the clock signal by approximately ?/2, and a sampler configured to sample the input signal in correspondence to one or more edges (such as one or more falling edges) of the sampling signal. In this way, the amplitude-modulated input signal may be sampled at its peak, or at least near its peak, thus ensuring high signal fidelity.

Abstract: A driving assistance apparatus, which executes a regeneration increasing control, includes a stop position specifying unit specifying a stop position, a calculation unit calculating a predetermined position at which a speed of the vehicle reduces to a predetermined speed, a determination unit determining a start point of a deceleration distance as a notification position when a distance between an end point of the deceleration distance and the predetermined position satisfies a predetermined condition, a notification unit notifying the driver to turn off the accelerator, and a regeneration control unit starting the regeneration increasing control when the vehicle has travelled the distance that satisfies the predetermined condition from the notification position.

Abstract: A motor controller includes an inter-vehicle sensor detecting an inter-vehicle distance between an own vehicle and a front vehicle, a speed sensor detecting a speed difference between a speed of the own vehicle and a speed of the front vehicle, an accelerator sensor detecting an accelerator pressing quantity, and a control portion controlling a regeneration torque of the motor based on the inter-vehicle distance, the speed difference, and the accelerator pressing quantity. When the control portion determines that the accelerator pressing quantity is less than or equal to a predetermined pressing quantity, the control portion determines that a speed-reduction request is generated. When the control portion determines that the inter-vehicle distance is no more than a first predetermined distance and when the own vehicle is in an approaching state, the control portion increases the regeneration torque of the motor, so as to generate a regeneration braking force.

Abstract: A Hybrid vehicle has an internal combustion engine, a first motor-generator, i.e., MG, a second MG, a battery section, and a control section. The control section performs first control which transmits power of the first MG to a drive shaft. The control section performs second control which starts the internal combustion engine by generating torque to the internal combustion engine using difference of rotational speeds of the first MG and the second MG, when the battery section fails while performing the first control. In the second control, the control section controls the second MG to generate electric power for driving the first MG. It is possible to provide a hybrid vehicle capable of starting the internal combustion engine even if the battery section becomes abnormal.
