摘要： A method for detecting a faulty cell in an electric battery pack includes the following steps: measuring the no-load voltage at the terminals of each cell of the battery pack; calculating the deviation between the no-load voltage measured at the terminals of the cell and an average known no-load voltage as a function of the number of days during which the battery pack was not used; calculating the difference between the calculated deviation and a quantity n·σ, n being an integer no lower than 1, and σ being a known standard deviation which is a function of the number of days during which the battery pack was not used; and detecting a faulty cell if the difference is greater than zero.

摘要： A method automatically controls a motor vehicle with wheels including at least two steered wheels. The method includes the following steps: the motor vehicle acquiring parameters relating to an obstacle avoidance trajectory, and a computer computing a provisional control instruction for an actuator for braking the steered wheels, based on the parameters and by way of a closed-loop controller. The method also includes the following steps: acquiring a lateral acceleration or a roll angle to which the motor vehicle is subject, and computing, in open-loop mode, a correction term or the provisional control instruction, based on the acquired lateral acceleration or roll angle.

摘要： An engine malfunction determination system includes a vehicle engine, an engine sensor system, an engine control module and an electronic display device. The engine sensor system has at least one sensor configured to detect an operation condition of the vehicle engine. The engine control module is in electrical communication with the sensor system to receive a detection signal from the engine sensor system regarding the operation condition of the vehicle engine. The engine control module is programmed to determine an anomaly in the detection signal. The electronic display device is programmed to display an indication of engine malfunction when the engine control module determines that the anomaly in the detection signal exceeds a predetermined threshold.

摘要： A vehicle speed/headway control function and a lane-keeping function are provided as driving assist functions to assist in a driving operation by a driver. A mode-switching controller is provided for switching between the modes. In the lane-keeping assist mode, it is assessed whether or not a traveling condition has been met that an actual vehicle speed of the host vehicle exceeds a speed limit of a roadway on which the host vehicle is traveling during lane-keeping travel in which “hands-off mode,” which allows the driver to remove their hands from the steering wheel, has been selected. The mode is switched from “hands-off mode” to “hands-on mode,” which has as a condition that the driver has their hands on the steering wheel, upon assessing that the traveling condition that the actual vehicle speed exceeds the speed limit has been met.

摘要： A vehicle motion control method controls a motion state of a vehicle during a vehicle transient motion in which an acceleration in a lateral direction is generated in the vehicle. The vehicle motion control method includes: setting a corrected longitudinal acceleration for correcting a basic longitudinal acceleration determined in accordance with a required driving force for traveling of the vehicle; and determining a target longitudinal acceleration from the basic longitudinal acceleration and the corrected longitudinal acceleration, and operating a traveling actuator of the vehicle based on the target longitudinal acceleration. A direction and a magnitude of the corrected longitudinal acceleration are determined from a viewpoint of suppressing a change in a posture of an occupant of the vehicle in a roll direction.
