  • Patent number: 8983751
    Abstract: Provided are a control system and method for stopping a vehicle, which reduce jerk when a vehicle controlled by an SCC system is stopped by the SCC system without a driver's manipulation. A desired target stop distance between a controlled vehicle and a front vehicle is set. Proposed is a formula for calculating a target acceleration in which a jerk is not caused when the target stop distance is maintained and then the controlled vehicle stops. By controlling the stop of the controlled vehicle according to the acceleration that has been calculated with the formula, the controlled vehicle is stopped without the occurrence of a jerk.

  • Patent number: 8981964
    Abstract: In this driving supporting device, the light color change cycle of a prediction object traffic signal is acquired on the basis of the light color change cycle of a prediction basis traffic signal installed before the prediction object traffic signal, and the light color state of the prediction object traffic signal when the vehicle arrives at the prediction object traffic signal is predicted on the basis of the light color state of the prediction basis traffic signal and the light color change cycle of the prediction object traffic signal. Thus, since the light color change cycle of the prediction object traffic signal is acquired on the basis of the light color change cycle of the prediction basis traffic signal, it becomes possible to predict a light color state even in the case of a traffic signal which cannot transmit information indicating its light color change cycle.

    Abstract: A platoon model allows improved prediction of preceding vehicle future state. In this context, the preceding vehicle is a vehicle immediately ahead of the host vehicle, and the dynamic state of the preceding vehicle was predicted based on data received from one or more vehicles in the platoon. The intelligent driver model (IDM) was extended to model car-following dynamics within a platoon. A parameter estimation approach may be used to estimate the model parameters, for example to adapt to different driver types. An integrated approach including both state prediction and parameter estimation was highly effective.

  • Patent number: 8942907
    Abstract: A method for avoiding reducing scoring of the brake disc or the brake drum of a vehicle driven under rainy conditions calculates a product of three parameters, and activates an automatic braking operation for the vehicle, regularly, whenever the product exceeds the pre-determined threshold level. The first parameter is a rain intensity based parameter, a measure of the current raining intensity. The second parameter is a brake-activation-free driving time parameter, representing the time elapsed since the braking system of the vehicle was activated last. The third parameter is a speed parameter, which represents a current speed of the vehicle. As the automatic braking operation is carried out, the particles of dust, water, snow and de-icing substances, adhered to the brake disc of the vehicle, and causing scoring of the brake disc, are quickly removed, thus, reducing disc scoring.

  • Patent number: 8855860
    Abstract: A vehicle behavior control apparatus disposed in a subject vehicle performs a steering angle control of the subject vehicle. The apparatus acquires lead vehicle information transmitted from a lead vehicle to determine a virtual shape of a road (i.e., a virtual road shape) based on a travel locus of the lead vehicle. A virtual road border distance is calculated as a distance from the subject vehicle to a road border of a virtual curve road positioned straight in front of the subject vehicle. The apparatus, calculates an appropriate turn radius for travel along the virtual curve road and, based on the appropriate turn radius, calculates an appropriate distance from the subject vehicle to the virtual road border positioned in front of the subject vehicle. A steering unit then controls a steering angle of the subject vehicle by maintaining the virtual road border distance with the appropriate distance.

    Abstract: A first travel controller of a control device for a vehicle sets a first target drive force based on preceding vehicle information to control a power source when a follow-up system is in an active state. A second travel controller sets a second target drive force based on a driver's operation to control the power source when the follow-up system is in an inactive state. A third travel controller sets a third target drive force that changes from the first target drive force toward to the second target drive force to control the power source when the follow-up system is switched from the active state to the inactive state. The third travel controller makes a difference between a change rate of the third target drive force set after the cancel operation and a change rate of the third target drive force set after the brake operation.

  • Patent number: 8849515
    Abstract: A collision avoidance system for assisting a driver in avoiding a collision between a host vehicle and obstacle. A processor recursively calculates a time-to-collision with the obstacle and an optimal collision avoidance path for avoiding the collision. The optimum collision avoidance path is recursively generated based on a position and speed of the host vehicle relative to the obstacle and an updated calculated time-to-collision. A sensing device determines whether the driver of the vehicle has initiated a steering maneuver to avoid the obstacle. A steering assist mechanism maintains the host vehicle along the optimum collision avoidance path. The steering assist mechanism applies a steering assist torque for producing steering adjustments to assist in guiding the host vehicle along the optimum collision avoidance path to the target lane. The steering assist torque generated by the steering assist mechanism is recursively adjusted based on a recent updated optimum collision avoidance path.

    Abstract: A method for cruise and/or range control of motor vehicles with range-controlled cruise control systems, wherein, during a determination of a desired acceleration value, for reaching a predefined speed and/or a predefined distance to a target object traveling ahead during a following travel, specific data of a target object traveling ahead and of a front object traveling in front of the target object are taken into account. As a function of the specific data of the target object driving ahead, a first desired pre-acceleration value is determined and, as a function of the specific data of the front object driving ahead, a second desired pre-acceleration value is determined. From the first desired pre-acceleration value and the second desired pre-acceleration value, by weighting the two desired pre-acceleration values, the relevant desired acceleration value is determined.
