摘要： A vehicle control device and a vehicle control method thereof are provided in the disclosure. Whether an autonomous driving assistance device, a steer-by-wire device of a vehicle, or a power supply of the vehicle has malfunctioned are determined. When it is determined that the autonomous driving assistance device, the steer-by-wire device, or the vehicle's power supply has malfunctioned while the vehicle is executing autonomous driving, vehicle weakening control is executed. In response to malfunctioning of the autonomous driving assistance device, the steer-by-wire device, or the power supply of the vehicle, and whether the vehicle switches to manual driving mode, target vehicle speed limit of the vehicle is adjusted.

摘要： A method for processing inflation defects of a tyre of a vehicle is disclosed, the tyre being equipped with sensors for measuring the pressure and the temperature of the internal cavity of said tyre. The pressure and the temperature of the internal cavity of the tyre are measured periodically and, as soon as an inflation defect of a tyre is detected, an alert is signalled to the driver of the vehicle, in which there is also transmitted to the driver of the vehicle a maximum speed setpoint: which, when the measured inflation pressure of the tyre is greater than or equal to a first inflation pressure threshold value p1, is a first maximum speed setpoint value V1; and which, when the measured inflation pressure of the tyre is less than said first pressure threshold value p1 and greater than or equal to a second pressure threshold value p2, decreases as a function of said measured inflation pressure of the tyre.

摘要： The subject matter of the invention is a method for detecting faults related to wheels of a motor vehicle in a driving situation, comprising: —a step (S1) of automatically determining a first series of corrective steering wheel angles applied successively to force the vehicle to follow a path parallel to a first rectilinear portion of a traffic lane; —a step (S2) of automatically detecting, from the corrective steering wheel angles of the first series, the presence of a fault affecting a pair of steering wheels of the vehicle; and, optionally: —a step (S3) of estimating a type of fault associated with the detected fault, a step (S4) of identifying the steering wheel of the pair of wheels affected by the fault; and —a step (S5) of generating a warning message for the attention of the driver of the motor vehicle, the message including the estimated type of fault and the wheel identified as having the fault.

摘要： Controlling maximum appliable positive and negative torque for a vehicle is provided. Vehicle data indictive of a driver torque request is received. Maximum appliable positive and negative torques for the vehicle are estimated. Responsive to the driver torque request being positive, the driver torque request is limited to the maximum appliable positive torque. Responsive to the driver torque request being negative, the driver torque request is limited to the maximum appliable negative torque.

摘要： A control system and method for a hybrid vehicle involve controlling a hybrid powertrain comprising an engine and a transmission having one or more electric motors and not comprising a decoupling mechanism therebetween, detecting an operating condition where the transmission is in neutral and the vehicle is moving at a speed less than a low speed threshold, and in response to detecting the operating condition: determining a desired propulsive torque of the powertrain, determining an actual propulsive torque at the driveline, calculating a torque difference between the actual and desired propulsive torques over a period, comparing the calculated torque difference to a first movement threshold, and when the calculated torque difference exceeds the first movement threshold, applying an electric parking brake (EPB) of the vehicle.

摘要： Systems and methods for operating a driveline of a hybrid vehicle are disclosed. In one example, powertrain output is limited or constrained so that powertrain output variation is limited to a desired level at different altitudes. The powertrain output may be constrained based on a ratio of a threshold electric machine torque to a threshold engine torque.

摘要： A computer in a vehicle can determine a first distance from a vehicle to a traffic object and receive, via a network interface, a second distance from a second vehicle to the traffic object and a third distance from the second vehicle to the vehicle. The computer can determine a fourth distance by triangulation based on the second distance and the third distance and pilot the vehicle based on combining the first distance and the fourth distance.

摘要： Cooling control systems described herein detect decreased operation of a cooling system of a vehicle, restrict movement of the vehicle without stopping movement responsive to decreased operation of the cooling system, and restrict movement of the vehicle by preventing the vehicle from traveling at a speed and/or power output for a non-zero designated period of time. This can allow for the vehicle to continue moving for a temporary period of time to avoid blocking traffic. Other control systems determine predicted distances and/or times that the vehicle can continue moving before coolant in the cooling system decreases below a designated threshold. Movement of the vehicle can be changed responsive to an upcoming distance and/or time that the vehicle is to travel exceeding the predicted distance and/or time. Other control systems modify a coolant flow rate based on differences between designated and ambient conditions.

摘要： In a host controller included in a vehicle control apparatus, a generator-torque-command generating unit monitors an abnormal operation of the engine on the basis of an engine power generation command and a detection signal of a rotating speed detector, switches, when the abnormal operation of the engine is detected, a generator torque command to the lowest value of a torque command value for abnormal time set in advance as the generator torque command, thereafter, gradually increases the generator torque command, and, after recording, as a torque limit value, the magnitude of the generator torque command (a torque command value for abnormal time 3) at the time when the abnormal operation of the engine is detected again, switches the generator torque command to a torque command value for abnormal time (a torque command value for abnormal time 2) having a value smaller than the torque limit value.
