20090024294 | SLIP CONTROL APPARATUS AND SLIP CONTROL METHOD - A slip control apparatus includes a driving torque calculating means calculating driving torque, a driving torque applying means applying the calculated driving torque to driving wheels, and a slip restraining means restraining slippage at each driving wheel when the slippage occurs at each driving wheel, wherein when the slippage occurs at each driving wheel, the driving torque calculating means calculates demanded torque and adds consumed driving torque, which corresponds to the driving torque consumed for restraining the slippage at each driving wheel by the slip restraining means, to the calculated demanded torque to calculate the driving torque. | 01-22-2009 |
20090055068 | VEHICLE DRIVE CONTROL DEVICE - A vehicle drive control device includes an initially determined request acceleration calculation means for calculating an initially determined request acceleration, an automatic drive control means for receiving the initially determined request acceleration and applying a predetermined torque to each wheel, a torque calculation means for calculating an allowable torque not causing a slip at each wheel when the allowable torque is applied thereto, on the basis of a vertical load applied to thereto and a friction coefficient of a road surface, a limit acceleration calculation means for calculating a limit acceleration acting on the vehicle in a case where the calculated allowable torque is applied to each wheel, and a request acceleration determination means for obtaining a request acceleration on the basis of the limit acceleration and the initially determined request acceleration, and for outputting the request acceleration, replacing the initially determined request acceleration, to the automatic drive control means. | 02-26-2009 |
20090132141 | TRACTION CONTROL SYSTEM AND METHOD FOR A VEHICLE - A system for a vehicle, comprising of a traction control system for adjusting powertrain output to reduce wheel slip; an input device located in said vehicle configured to identify an environmental condition; and a powertrain controller to control powertrain output based on actuation of a pedal of the vehicle by the driver, where a relationship between powertrain output and pedal actuation is adjusted in response to said input device. | 05-21-2009 |
20100161194 | SYSTEM AND METHOD FOR ACTIVE TRACTION CONTROL OF A VEHICLE - A method for active traction control of a vehicle can be performed to optimize corner exiting performance of a vehicle that is operating in a high performance or racing environment. The method estimates a real-time tire traction value during operation of the vehicle, computes a remaining tire traction value based upon a comparison of the estimated real-time tire traction value to a total available tire traction value, and calculates a traction system torque limit from the remaining tire traction value. The calculated torque limit can then be used to limit the actual traction system torque of the vehicle as needed in a real-time manner. | 06-24-2010 |
20110295481 | METHOD FOR SETTING A WHEEL TORQUE IN A VEHICLE - In a method for setting a wheel torque in a vehicle, a setpoint value for a slip-adhesion coefficient gradient for one wheel of one vehicle axle is ascertained, and the wheel torque is set in such a way that the actual value of the gradient is approximated to the setpoint value. | 12-01-2011 |
20120022761 | Traction Control System in a Vehicle, Vehicle Including Traction Control System, and Traction Control Method - A traction control system in vehicle comprises a detector for detecting a monitored value which changes according to a degree of a drive wheel slip; a condition determiner for determining whether or not the monitored value meets a control start condition and whether or not the monitored value meets a control termination condition; and a controller for executing traction control to reduce a driving power of the drive wheel during a period of time from when the condition determiner determines that the monitored value meets the control start condition until the condition determiner determines that the monitored value meets the control termination condition; the condition determiner being configured to set at least the control start condition variably based on a slip determination factor which changes according to a vehicle state and such that the control start condition changes more greatly according to the vehicle state than the control termination condition. | 01-26-2012 |
20130096797 | METHOD OF CONTROLLING VEHICLE WHEEL AXLE TORQUE AND CONTROL SYSTEM FOR SAME - A method of controlling torque on a vehicle wheel axle includes comparing a torque intervention request to a predetermined minimum axle torque for a current vehicle speed and a current direction of motion of the vehicle. The predetermined minimum axle torque decreases as vehicle speed in an operator-selected direction of motion increases. An arbitrated axle torque is calculated based on an operator-requested torque, the current vehicle speed, the current direction of motion, and the greater of the torque intervention request and the predetermined minimum torque. Axle torque is applied to the vehicle's wheel axle based at least partially on the arbitrated axle torque. | 04-18-2013 |
20150134221 | CONTROL METHOD, COMPUTER PROGRAM AND CONTROL DEVICE OF A TRACKED VEHICLE - A control method of a tracked vehicle having a track belt and configured to advance the tracked vehicle provides for acquiring the driving speed of the tracked vehicle; acquiring the speeds of the tracks with respect to the tracked vehicle; calculating a range of expected values of traveling speed as a function of speed of the track; and varying the speed of the track when the traveling speed of the tracked vehicle is outside the range of expected values. | 05-14-2015 |
