摘要： In a hybrid vehicle including an engine, a motor, a generator, and a battery that is electrically connected to the motor and the generator, an ECU performs “battery-less travel control” enabling the vehicle to travel when a fault occurs in the battery by disconnecting the battery from an electrical system including the motor and the generator and driving the motor using power that is generated by the generator using the power of the engine. When the battery-less travel control is underway and a vehicle speed V exceeds a vehicle speed limit Vsh, the ECU implements a vehicle speed limitation. As a result, a control mode of the motor is less likely to shift to a rectangular control mode during the battery-less travel control.
摘要翻译：在包括发动机，电动机，发电机和电连接到电动机和发电机的电池的混合动力车辆中，ECU执行“无电池行驶控制”，使得当电池发生故障时车辆行驶通过将电池从包括电动机和发电机的电气系统断开，并且使用发动机的功率利用发电机产生的电力来驱动电动机。当无电池行驶控制正在进行并且车速V超过车速限制Vsh时，ECU执行车速限制。结果，在无电池行驶控制期间，马达的控制模式不太可能转换到矩形控制模式。

摘要： In a vehicle that includes an engine, a motor, a generator, a battery electrically connected to the motor and the generator, and a transmission provided between the motor and an output shaft coupled to a drive wheel, an ECU executes “battery-less travel control” in which, at the time of a failure of the battery, the battery is isolated from the motor and the generator, the generator is caused to generate electric power by generating a torque, corresponding to an accelerator pedal operation amount, from the generator, and the vehicle is caused to travel by driving the motor using the electric power generated by the generator. The ECU suppresses losing a balance of input and output electric powers between the generator and the motor by filtering the accelerator pedal operation amount when a vehicle speed exceeds a limit vehicle speed during the battery-less travel control.

摘要： A tractor includes: a work machine connected to a vehicle body; an elevator mechanism configured to move the work machine up and down; an electric motor; a battery; an electric leakage detection circuit configured to detect electric leakage in the battery; and a control device. The control device controls the elevator mechanism either in a lowered state or a raised state, the lowered state being a state where the work machine is placed at a position making contact with a ground, the raised state being a state where the work machine is placed at a position distanced from the ground. In a case where the electric leakage detection circuit detects electric leakage in the battery at the time when the elevator mechanism is in the lowered state, the control device performs a state change process of bringing the elevator mechanism into the raised state.

摘要： A display system includes an instrument panel and an ECU for controlling the instrument panel so that the instrument panel displays an indication related to a battery. The ECU controls the instrument panel so that the instrument panel continuously displays a second indication. The ECU also controls instrument panel so that instrument panel does not display a first indication when a predetermined condition does not hold true, and displays the first indication when the predetermined condition holds true, the predetermined condition being a condition that a display-related user operation has been performed. The first indication can be prevented from being mistaken as the second indication, without requiring a display-related user operation.

摘要： An ECU performs processing including obtaining a full charge capacity when a cooling apparatus remains stopped, showing textual information that inquires about whether or not cooling can be carried out when a battery temperature is equal to or lower than a threshold value TB(1), when the full charge capacity is equal to or lower than a threshold value C(1), and when the battery temperature is equal to or higher than a threshold value TB(2), carrying out battery cooling control when a request for carrying out cooling has been issued, and maintaining a standstill state of the cooling apparatus when no request for carrying out cooling has been issued.

摘要： A vehicle includes: an engine; an exhaust pipe through which exhaust gas from the engine is released; a battery pack located near the exhaust pipe; and an ECU that executes, during limp-home traveling of the vehicle, control in which the battery pack is not charged and discharged, and output suppression control in which output of the engine is suppressed. In the output suppression control, when the catalyst temperature is above a threshold value, the ECU suppresses the output of the engine, as compared to when the catalyst temperature is below the threshold value, while maintaining a state in which the engine can output power.

摘要： An ECU sets a SOC estimated from an OCV at the time of activating a system of a vehicle as an initial SOC value in the case where the SOC during a stop of the system is higher than a first SOC, which represents the SOC estimated from the OCV at the time of activating the system by using a discharging curve line, or the SOC during the stop of the system is lower than a second SOC, which represents the SOC estimated from the OCV at the time of activating the system by using a charging curve line. The ECU sets the SOC during the stop of the system as the initial SOC value in the case where the SOC during the stop of the system is equal to or lower than the first SOC and is equal to or higher than the second SOC.

摘要： A secondary battery system includes an assembled battery that includes a plurality of blocks that are connected in series to one another. Each of the plurality of the blocks includes same number of cells that are connected in parallel to one another. A control device is configured to calculate an internal resistance ratio and a protection current. The internal resistance ratio is a value obtained by dividing the higher one of internal resistances by the lower one of the internal resistances of two of the plurality of the blocks. The protection current is a value obtained by multiplying the internal resistance ratio by a current value of the assembled battery detected by a current sensor. The control device is configured to perform the charge-discharge control based on the protection current.
