    Abstract: A motor control unit, a control system, and a storage medium. The method of the present invention is applied to the motor control unit and comprises: when a vehicle is in a high-voltage power-on state, obtaining a plurality of effective temperature values for the same motor system; determining a corresponding initial temperature value according to each effective temperature value; determining the minimum value among all calculated initial temperature values as an initial environment temperature; when the vehicle is in a driving state and each initial temperature value is less than or equal to respective corresponding threshold, and the current temperature of a motor no longer rises, calculating differences between the current temperature of the motor and the corresponding initial temperature value and between the current temperature of a cooling liquid and the corresponding initial temperature value; calculating a temperature calibrate amount for the environment temperature according to the calculated differences.

    Abstract: A vehicle is equipped with an electric storage device, a drive motor, an auxiliary that can be driven by a regenerative electric power, and a control unit. The control unit performs a non-chargeable control for causing the auxiliary to consume the regenerative electric power when the electric storage device is in a non-chargeable state, and performs a specific maneuver control for causing the auxiliary to consume the regenerative electric power even when the electric storage device is in a chargeable state in the case where an operational maneuver for making a change to an operation mode in which a larger amount of the regenerative electric power is generated is performed with the regenerative electric power generated.

    Abstract: A window heating system for providing current to a heating element includes a first sensor, a second sensor, and a sensor selection module configured to determine a state of the first and the second sensors. The sensor selection module includes a first comparator associated with the first sensor and configured to determine whether a condition of the first sensor is satisfied. The window heating system also includes a controller configured to control current to the heating element based on the second sensor when the first comparator determines the condition of the first sensor is not satisfied.

    Abstract: The invention relates to a fuel cell vehicle (200), in which the driver has more influence on the consumption and the dynamic of the vehicle (200). This is achieved by the fuel cell vehicle (200) comprising at least one sensor for detecting a first driver input and a control unit (60). The control unit (60) is configured to operate the fuel cell vehicle (200) in one of a plurality of operating modes depending on the first driver input, wherein a power consumption PAC of the air-conditioning system (70), an operating range of the fuel cell stack (10), and a transfer function for determining the power demand PEM from the second driver input are varied depending on the selected operating mode. It is provided that the driver has at least five different operating modes available, which differ in particular with respect to the available driving dynamic, the fuel consumption, and the adjustable comfort.
