A method of controlling the stability of a vehicle. The method comprises acquiring an actual value of a vehicle stability parameter and determining a difference between the actual parameter value and a target value of that stability parameter. The method further comprises applying a damper intervention threshold to the difference between the actual and target parameter values, the damper intervention threshold representing a magnitude of the difference between the actual and target parameter values at which damper intervention may be utilized to mitigate a potential over-steer or under-steer condition. The method still further comprises predicting the occurrence of an over-steer or under-steer condition when the damper intervention threshold is exceeded.

An object of the invention is to provide a traveling control system capable of reducing discomfort or uneasiness felt by a driver or an occupant in automatic traveling control of a vehicle. The invention provides a traveling control system including an on-vehicle control device that is mounted on a vehicle and performs traveling control on the vehicle and an on-vehicle display device that is connected to be communicable with the on-vehicle control device and presents information to an occupant of the vehicle through screen display or audio output. The on-vehicle control device acquires externality recognition information recognized by an externality sensor and/or out-of-vehicle communication, decides driving behavior content to be taken by the vehicle based on the externality recognition information, specifies a driving behavior cause which is a reason why the driving behavior content is decided, and outputs the driving behavior content and the specified driving behavior cause. The on-vehicle display device acquires the driving behavior content and the driving behavior cause output by the on-vehicle control device and notifies of the driving behavior content and the driving behavior cause through screen display or audio output.

When starting an automatic brake in preparation of collision avoidance, a sense of discomfort given to a driver should be reduced as much as possible. To solve such a problem, a hybrid ECU 50 reads mode information during regenerative braking (S42), and gradually decreases regenerative braking force (S45) when a friction braking force control in accordance with a preparatory mode is started (S44: Yes). Thereby, a sudden change of vehicle deceleration can be prevented. On the other hand, the hybrid ECU 50 makes regenerative braking force disappear immediately (S46) when a friction braking force control in accordance with a collision avoidance braking mode is started during regenerative braking (S43: Yes). Thereby, the vehicle can be slowed down with a deceleration for collision avoidance.

Vehicles feature various forms of automated driving control, such as speed control and braking distance monitoring. However, the parameters of automated control may conflict with the user driving behaviors of the user; e.g., braking distance maintained with respect to a leading vehicle may seem overcautious to users who prefer shorter braking distances, and unsafe to users who prefer longer braking distances. Presented herein are techniques for controlling vehicles according to the user driving behaviors of users. While a user operates a vehicle in a driving context, a device monitors various driving features (e.g., acceleration or braking) to determine various user driving behaviors. When requested to control a driving feature of the vehicle, a controller may identify the user driving behaviors of the user in the driving context, and control the driving features according to the user driving behaviors, thus personalizing automated driving to the preferences of the user.

Systems and methods use cameras to provide autonomous navigation features. In one implementation, a method is provided for navigating a vehicle. The method may include acquiring, using at least one image capture device, a plurality of images of an area in the vicinity of the vehicle; and determining from the plurality of images a first lane constraint on a first side of the vehicle and a second lane constraint on a second side of the vehicle opposite to the first side of the vehicle. The method may further include causing the vehicle to travel within the first and second lane constraints based on the area in the vicinity of the vehicle.
摘要:
In a first aspect, the invention relates to a method for resuming the movement of a motor vehicle after unforeseen stopping in an automated parking process by means of a parking assistance system having automated longitudinal and transverse guidance. According to the invention, if the vehicle is stopped, a decision is made about a resumption of movement of the vehicle in the prior direction of travel that existed before the vehicle was stopped. According to a preferred design of the invention, the decision is made in dependence on the remaining travel path from the current position to the next planned stopping point of the trajectory lying in the prior direction of travel. A stopping point of the trajectory can be a reversal point or the final parking position, for example. If the decision is positive, the movement of the vehicle is resumed in the prior direction of travel. If the decision is negative, the movement of the vehicle is resumed against the prior direction of travel. Alternatively, it is also conceivable that, in the case of a negative decision, the movement of the vehicle is not resumed and the parking process is ended.
