    摘要： A map data generation apparatus is provided as follows. Probe data are collected from a plurality of vehicles. An integration process is performed to generate an integrated map data by integrating the collected probe data for each of data management units corresponding to (i) road sections, (ii) road links, or (iii) meshes into which a map is divided. A comparison process is performed to obtain a difference by comparing the generated integrated map data with a basic map data. The basic map data is updated based on the obtained difference. The integrated map data for a first data management unit is generated in response to a required number of the probe data being collected for the first data management unit. The required number of the probe data is set depending on a road type in the first data management unit.

    摘要： A system and method for providing fault mitigation in a vehicle system having high side drivers (HSDs) and low side drivers (LSDs) are provided. The system includes a first HSD and a plurality of first LSDs. The system also includes a selected first plurality of actuators, with each actuator connected to the first HSD and connected to a respective one of the first LSDs to operate in a first operational mode. The system further includes a second HSD and a plurality of second LSDs. The system also includes a selected second plurality of actuators, with each actuator connected to the second HSD and connected to a respective one of the second LSDs to operate in a second operational mode. When a failed component sets a fault, the corresponding HSD is turned off and the other HSD is turned on, enabling the vehicle system to operate in the non-faulted operational mode.

    摘要： The present disclosure relates to fault management apparatus and method for an independently controlled steering system in a four wheel drive system. The apparatus includes: a steering system unit that is disposed at four wheels of a vehicle, controls steering of the wheels, and collects and transmits the state information of the wheels; and a control unit that controls the steering system unit in accordance with the state information transmitted from the steering system unit. According to the present disclosure, when there is a fault in one or more wheels of a four wheel drive vehicle, it is possible to stabilize the vehicle body by actively adjusting the steering angles of the wheels that normally work and the speed of the vehicle in accordance with the fault environment.

    摘要： Illustrative example embodiments provide a motor vehicle including an actuator means operable to provide motive power to the vehicle. The vehicle is operable automatically to switch off and subsequently to restart the actuator means during a drivecycle thereby to reduce an amount of time the actuator means is on during a given drivecycle. The vehicle may be placed in an eco-stop condition by driver-operated brake means in which the vehicle is held stationary and the actuator means is off, The vehicle. is operable automatically to perform an eco-start operation in which the actuator means is restarted when the driver signals release of the brake means. When an eco-start is performed the vehicle is arranged automatically to continue to be held stationary by means of the brake means while the actuator means is restarted. If the actuator means fails to restart, the vehicle is arranged automatically to assume a failed start condition in which the vehicle continues to be held stationary.
