    摘要： A method of implementing a preparation mode capable of improving driving performance of a vehicle by warming up a vehicle component before racing is provided. The method includes acquiring vehicle state information detected by a vehicle state detector while the vehicle is driven on a circuit before racing after entering the circuit, and determining a tire slip rate from a wheel speed and a vehicle speed in the vehicle state information. The method also includes determining whether a current vehicle driving state satisfies a preset preparation mode entry condition based on the vehicle state information and the tire slip rate. The method further includes, when the current vehicle driving state satisfies the preset preparation mode entry condition, controlling an operation of a warm-up device for warming up a vehicle component that determines driving performance of the vehicle, and warming up the vehicle component.

    摘要： A control device executes caster angle change control for controlling a driving force applying device or each of the driving force applying device and a braking force applying device to reduce a caster angle of a steered tire-wheel assembly when a steering request is received in a stopped state or in a creeping state without exceeding a predetermined vehicle speed at a point starting from the stopped state. In the caster angle change control, the control device applies, to one tire-wheel assembly out of a front tire-wheel assembly and a rear tire-wheel assembly, a driving force in a direction toward the other tire-wheel assembly and applies, to the other tire-wheel assembly, a braking force or a driving force in a direction toward the one tire-wheel assembly to achieve the stopped state or the creeping state in response to a request for acceleration or deceleration.

    摘要： An electronic anomaly detection unit for use in a vehicle includes an input component for capturing an input variable, wherein the input variable contains state information for at least one component of the vehicle, a memory component for storing state values based on the input variable, a selection component for selecting selected state values from the stored state values, an association component for associating the selected state values with predefined values, wherein the predefined values define a normal state of the component of the vehicle, and a decision component for deciding whether there is an anomalous behavior in the at least one component of the vehicle, based on the association, wherein one or more of the input component, the memory component, the selection component, the association component and the decision component are implemented in hardware.

    摘要： Techniques are discussed herein for detecting and measuring faults within vehicle drive systems. In various implementations, actuator feedback monitors and/or vehicle performance monitors are used individually or in combination to determine faults within acceleration systems, braking systems, and/or steering systems of a vehicle. Different monitors may use different algorithms, models, and input data from the vehicle during operation, to compare a predicted drive system output to a corresponding measured output. Additionally, monitors may include associated sets of disable conditions used to distinguish drive system faults from other driving conditions. The outputs from actuator feedback monitors, vehicle performance monitors, and disable conditions may be analyzed to detect drive system faults and control the vehicle to address the faults and control the safe operation of the vehicle.
