A vehicle driving support device issues an alert to notify a driver of a vehicle that there is a possibility of occurrence of a situation in which the vehicle is not able to travel along a lane. The vehicle driving support device issues an alert when an alert condition that a rate of increase in a lateral acceleration of the vehicle is equal to or larger than a predetermined rate of increase is satisfied.

An anticipating module for a device for controlling, in real time, the path of a motor vehicle includes a sub-module for computing a turning command for compensating for the curvature of a bend in the lane of the vehicle and a variable-gain device that is connected to an output of the computing sub-module. The gain of the variable-gain device is connected to a controller to adjust the gain so as to decrease the lateral offset between the centre of gravity of the vehicle and the centre of the lane of the vehicle depending on the result of the comparison of components of a vector of current measurements of state variables of the device to one another and to a detection threshold, the output of the variable-gain device being the steering command for compensating for the curvature of the bend.

Systems and methods for determining whether to use engine start-stop systems during trail or other off-road driving are provided. Systems and methods may utilize various vehicle sensors (e.g., lidar, forward-facing cameras, accelerometers, sonar sensors, etc.) to detect when it is appropriate to command engine stop for fuel economy while driving off-road. To determine appropriateness, the vehicle may evaluate obstacles, ground clearance, and/or vehicle inclination. A method may include measuring accelerations/inclinations of a vehicle, comparing an acceleration value of each acceleration to an acceleration threshold, and disabling a start-stop system of the vehicle based on at least one acceleration value exceeding the acceleration threshold. A system may include an accelerometer configured to measure accelerations of a vehicle, and a logic device configured to compare an acceleration value of each acceleration to an acceleration threshold, and disable a start-stop system based on at least one acceleration value exceeding the acceleration threshold.
