Abstract:
Improved is determination accuracy on whether or not a driver is erroneously performing an accelerator operation instead of a brake operation. A pedal opening degree PPO by a driver and a continuation time Te for which the pedal opening degree PPO is greater than an opening degree threshold value Pth are detected. When the continuation time Te exceeds a time threshold value Tth, it is determined that the driver is erroneously performing an accelerator operation instead of a brake operation. A vehicle speed V of a vehicle, a rising gradient Sr of a road surface, and an accelerator operation time Tp operated by the driver are detected. The opening degree threshold value Pth is made variable in accordance with the vehicle speed V, the rising gradient Sr, and the operation time Tp. The time threshold value Tth is made variable in accordance with the vehicle speed V, the rising gradient Sr, and the operation time Tp.
Abstract:
A driving assistance apparatus 1 includes: a brake-on-vehicle-speed estimation unit 41, which estimates a brake-on vehicle speed Vbrk as a vehicle speed at which a driver of a vehicle 2 starts a brake operation, based on a road surface gradient θ and an approaching vehicle speed Vin; a deceleration-operation-point calculating unit 42, which calculates location information of a deceleration-operation point where the driver of the vehicle 2 starts a deceleration operation, based on the estimated brake-on vehicle speed Vbrk; and a deceleration-assistance control unit 43 and a HMI device 5, which present driving assistance information for prompting the driver of the vehicle 2 to perform the deceleration operation corresponding to the calculated location information of the deceleration-operation point and a running position of the vehicle 2, as information presentation means. Thus, when the driving assistance for teaching the driver the deceleration operation is performed, the driver can be less likely to feel uncomfortable.
Abstract:
A device and method for estimating the charge of a motor vehicle. A device for estimating the charge of a combustion or hybrid powered motor vehicle comprising an automatic transmission, comprising a module (3) for determining the charging of the vehicle capable of determining if the vehicle is charged and an activation module (4) for activating a programme for controlling the automatic transmission (2) on the basis of the determination of the charging of the vehicle (Cons _charge ). The module (3) for determining the charging comprises a first unit (5) for estimating a first slope value on the basis of the acceleration of the vehicle derived from the driving force and the longitudinal acceleration (A total) of the vehicle, a second unit (6) for estimating a second slope value (C slope) on the basis of the moment of inertia (J) applied to a non-driving wheel of the vehicle and the engine and resistant torques (C e, C res) and a third unit (7) for determining the charging of the vehicle (Cons _charge ) on the basis of the first and second slope values (A slope, C slope).

Abstract:
The present invention provides a vehicle control system (110) and method operable to control at least one vehicle subsystem (120, 130, 140, 150, 160) to operate in a selected one of a plurality of subsystem configuration modes. The control system is operable in a plurality of driving modes in each of which it is arranged to select the subsystem configuration mode of the at least one vehicle subsystem in a manner suitable for a respective type of driving surface. The control system uses the output of an imaging device (115) capturing the driving surface on which the vehicle is driving or will likely be driving.
Abstract:
Um eine vorausschauende Fahrweise zu erleichtern, wird ein Ausrollweg eines des Fahrzeugs in Abhängigkeit von Werten für eine Mehrzahl von Fahrwiderstandsparametern ermittelt. Eine Bewegung (53) des Fahrzeugs wird zu mehreren Zeiten während eines Ausrollvorgangs (21), bei dem ein Freilauf-Betriebszustand oder ein Schubabschaltungs-Betriebszustand des Fahrzeugs vorliegt und sich das Fahrzeug ausgehend von einer Anfangsgeschwindigkeit bis zu einer Zielgeschwindigkeit verlangsamt, erfasst. Ein adaptierter Wert wird für wenigstens einen Fahrwiderstandsparameter der Mehrzahl von Fahrwiderstandsparametern in Abhängigkeit von der erfassten Bewegung (53) des Fahrzeugs bestimmt. Der adaptierte Wert für den wenigstens einen Fahrwiderstandsparameter wird zum nachfolgenden Ermitteln eines weiteren Ausrollwegs (56) ausgehend von einer weiteren Anfangsgeschwindigkeit (54) bis zu einer weiteren Zielgeschwindigkeit (55) verwendet.
