    摘要： The present invention protects a high voltage battery in a hybrid electric vehicle. More particularly, it makes it possible to prevent a battery from being overcharged when a motor or an inverter system breaks, with the hybrid vehicle traveling. The technique for protecting a high voltage battery in a hybrid electric vehicle illustratively comprises: checking whether a motor functions properly; setting a virtual acceleration pedal value and keeping a present desired shifting map, when the motor breaks; determining a desired shifting stage according to the present desired shifting map based on the virtual acceleration pedal value; and, in certain embodiments, switching or keeping the engine control mode by comparing a value of a predetermined maximum engine speed region with the present engine speed in order to prevent high-speed rotation of the motor.

    摘要： A vehicle includes electrical components, current sensors which determine current flowing through the electrical components, and a control system. The control system calculates and records error index values over an interval using the currents. The control system increments a first counter with every sample in the series, increments a second counter whenever a given error index value exceeds a calibrated high threshold, and decrements the second counter whenever the given error index value is less than a calibrated low threshold. A control action, e.g., recording a PASS or FAIL value, executes when either the absolute value of the second counter or the present value of the first counter reaches a corresponding limit or threshold. A method enhances the robustness of a hybrid vehicle torque security diagnostic using the control system. The vehicle and method use a signed X of Y debouncing or error signal processing method as noted above.

    摘要： A data communication system has a pair of signal lines which connects a plurality of controllers on a vehicle. At least one controller has a failure detector which detects data communication failure. At least one controller has a fall-back detector which detects fall-back state in which data communication is performed by using only one signal line. At least one controller has a high-level fail-safe module which restricts driving of the vehicle in response to a detection of the failure. The controller also has a low-level fail-safe module which performs precautious fail-safe control, which is less restrictive than that performed by the high-level fail-safe module, in response to a detection of the fall-back state.

    摘要： For the operation of a motor vehicle (2), when a critical (CRIT) operation state (STATE) of the motor vehicle (2) and/or a drive system (4) of the motor vehicle (2) is detected in which an operation error (ERROR) can occur, a driver of the motor vehicle (2) is signaled (SIG) that there is a critical (CRIT) operation state (STATE). When the operation error (ERROR) occurs, the system is switched into a limited operation (LIMIT) of the drive system (4).
