20080255729 | Steering Assist System and Vehicle Mounted with the Same - An object of the present invention is to provide a steering assist system capable of showing a driver an appropriate direction of steering operation in advance and correctly, and without impairing safety, and shortening an operation time during collision avoidance, in particular, reducing an idle running time. It is another object of the present invention to provide a vehicle mounted with such a steering assist system. | 10-16-2008 |
20090099728 | CONTROL APPARATUS FOR AVOIDING COLLISION - A collision avoiding control apparatus has a side acceleration command calculator unit for calculating a side acceleration command by judging whether an obstacle is to be avoided, by calculating a distance of the obstacle capable of being avoided, in accordance with a distance and width of the obstacle in front of a vehicle and a vehicle speed, and if it is judged that the obstacle is to be avoided, calculating a side acceleration necessary for a vehicle side motion amount to satisfy the width, in accordance with the distance and width and the vehicle speed, and a steering angle calculator unit for calculating in a predictable manner a vehicle steering angle from the side acceleration command calculated by the side acceleration command calculator unit. | 04-16-2009 |
20100161164 | ELECTRIC VEHICLE WITH PITCH CONTROL DEVICE - Changes in the number of passengers or in load cause significant changes in vehicle weight, thus making it impossible to appropriately suppress a pitching motion of a vehicle chassis, hence rendering a necessary driving torque difficult to ensure, resulting in a decrease in drivability being insuppressible. An electric vehicle with a drive including a motor and a controller comprises a pitching quantity detector that detects a magnitude of a pitching motion of the vehicle, a vehicle weight determination unit that determines weight of the vehicle, a torque correction calculator that uses a traveling state of the vehicle and the determined vehicle weight to change a driving torque output from the drive, and a control gain varying element that adjusts a control gain of the torque correction calculator according to a magnitude of the vehicle weight value output from the vehicle weight determination unit. | 06-24-2010 |
20100204887 | TURNING MOTION ASSISTANCE DEVICE FOR ELECTRIC VEHICLE - Disclosed herein is a turning motion assistance device for an electric vehicle, adapted to effectively reduce tire wear of the vehicle while at the same time ensuring appropriate turning response. | 08-12-2010 |
20110010040 | SYSTEM FOR MONITORING FOR RISK OF ROAD SHOULDER COLLAPSE, AND TRANSPORT VEHICLE - Disclosed herein is a shoulder collapse risk monitoring system capable of alerting a driver to a risk of a road shoulder collapse during approach operations to the shoulder. | 01-13-2011 |
20120239234 | ELECTRIC VEHICLE WITH PITCH CONTROL DEVICE - An electric vehicle includes a pitching state quantity detector for detecting quantity of a pitching-motion of the vehicle, a vehicle weight determiner, a pitching target quantity calculator for calculating a target quantity of a pitching motion at least from the determined vehicle weight, and a torque correction calculator for increasing/reducing a driving torque output, according to a particular differential between the detected pitching-motion state quantity and the calculated target quantity. | 09-20-2012 |
20120239257 | DUMP VEHICLE OVERTURN PREVENTING DEVICE - Provided is an overturn preventing device for a dump vehicle equipped with a body ( | 09-20-2012 |
20130103244 | DRIVING FORCE CONTROL DEVICE FOR ELECTRIC VEHICLE - Disclosed is a driving force control device that includes a determination section ( | 04-25-2013 |
20130116874 | PITCH CONTROL DEVICE FOR ELECTRIC VEHICLE - To suppress a change in a vehicle's attitude due to a pitch motion during vehicle braking, a pitch control device for an electric vehicle can prevent discontinuous negative acceleration from occurring at a moment of the vehicle stopping by appropriately controlling a braking force of the vehicle, thereby effectively controlling the pitch motion of the vehicle, and can enhance steering stability while ensuring riding comfort for passengers, even when traveling resistance significantly changes according to road surface gradient and when the vehicle weight significantly changes with increases/decreases in the number of drivers and in the quantity of goods loaded. | 05-09-2013 |
20140129097 | DUMP VEHICLE OVERTURN PREVENTING DEVICE - Provided is an overturn preventing device for a dump vehicle equipped with a body and hoist cylinders. The dump vehicle overturn preventing device comprises: a loaded weight estimation unit which estimates loaded weight on the body; a vehicle rotation moment calculation unit which calculates a vehicle rotation moment Mb caused by movement of the dump vehicle's load upon discharging of the load; a reference moment calculation unit which determines a reference moment Ms not greater than an overturn threshold moment MI which is the minimum value of a rotation moment required to lift the front wheels off the ground; a judgment unit which judges whether or not the vehicle rotation moment Mb has exceeded the reference moment Ms; and a display device which notifies the driver that there is a probability of an overturn of the vehicle when the vehicle rotation moment Mb is judged to have exceeded the reference moment Ms. The device thus prevents overturning of the vehicle caused by the load sliding down from the body in a lump. | 05-08-2014 |
