Apparatus for controlling four-wheel drive vehicle
An apparatus for controlling a four-wheel drive vehicle includes a tire friction circle calculator that calculates the size of a tire friction circle of each wheel on the basis of vehicle information including a tire vertical load, a resultant force calculator that calculates the magnitude of a resultant force of tire lateral and longitudinal forces for each wheel, a tire-friction-force usage rate calculator that calculates a tire-friction-force usage rate of each wheel that is the ratio of the magnitude of the resultant force to the size of the tire friction circle, and a driving-braking force adjustment controller that adjusts driving force or braking force applied to each wheel. When the tire-friction-force usage rate of any wheel exceeds a predetermined threshold of less than one, the driving-braking force adjustment controller restrains an increase in the driving force or the braking force of the wheel while increasing the driving force or the braking force of at least one of the other wheels that is selected on the basis of driving operation information indicative of the state of a driving operation by a driver.

A vehicle according to an exemplary embodiment of the present invention includes an electronic chassis control system configured for an electronic control suspension (ECS), a motor driven power steering system (MDPS), an electronic stability control (ESC), and an all wheel drive (AWD), and an integrated controller implementing an integrated avoidance control in which controls for each of the MDPS, the ESC, and the AWD according to an emergency avoidance control of the ECS in the forward collision situation, wherein it is possible to safely and rapidly avoid risk of forward collision, and cooperative control performance of the ECS and the AWD, the ESC and the MDPS is optimized by applying an emergency grade to the integrated avoidance control.
Parallel hybrid vehicle launch torque control
System and methods are provided for improving launch performance of a hybrid vehicle. During a stall condition prior to launch, the engine of the hybrid vehicle can produce engine torque beyond a standard stall torque limit. Negative motor torque that offsets the increase in engine torque in accordance with the standard stall torque limit is produced by the motor. This results in loading the automatic transmission of the hybrid vehicle with additional torque that would otherwise not be possible. During a launch condition following the stall condition, the motor torque is dropped to 0 Nm, and the brakes are released, allowing the hybrid vehicle to accelerate. The full torque generated by the engine is provided to the automatic transmission and used to drive one or more wheels of the hybrid vehicle.
HILL DESCENT SYSTEM FOR VEHICLE AND CONTROL METHOD THEREOF

Vehicle control device
A vehicle control device comprises: a downshift control part (51) configured, upon issuance of a downshift request for downshifting an automatic transmission (200), to execute a downshift control of downshifting the automatic transmission (200) and driving an engine torque regulating mechanism to increase an output torque of an engine (10); a vehicle attitude control part (53) configured, upon satisfaction of a condition that the vehicle is traveling and a steering angle-related value pertaining to a steering angle of a steering device increases, to execute a vehicle attitude control of reducing the output torque of the engine (10) to generate deceleration of the vehicle so as to control vehicle attitude; and a downshift suppression part (55) configured, when the vehicle attitude control is executed, to suppress the execution of the downshift control.
Devices, systems, and methods for transmitting vehicle data
Systems and methods for coordinating and controlling vehicles, for example heavy trucks, to follow closely behind each other, or linking to form a platoon. In one aspect, on-board controllers in each vehicle interact with vehicular sensors to monitor and control, for example, relative distance, relative acceleration or deceleration, and speed. In some aspects, a lead vehicle can wirelessly transmit information from various electronic control units (ECUs) to ECUs in a rear vehicle. A rear vehicle can then apply transformations to the information to account for a desired following distance and a time offset. ECUs onboard the rear vehicle may then be controlled based on the ECUs of the lead vehicle, the desired following distance, and the time offset.
