摘要： A method for determining road bank angle in vehicle includes a lateral acceleration sensor (22) that generates a first signal corresponding to lateral acceleration. A yaw rate sensor (18) generates a second signal corresponding to a yaw rate signal. A controller (14) coupled to the sensors performs the step of calculating a first bank angle estimate dependent on the first signal, calculating a second bank angle estimate dependent on the second signal, calculating a third bank angle estimate dependent on both the first and second signals, calculating a dynamic compensation factor based as a function of the first bank angle estimate, the second bank angle estimate and the third bank angle estimate, decomposing the third bank angle estimate into a plurality of third bank angle frequency layers, reducing each of the plurality of third bank angle frequency layers in response to a multiplicative factor, said multiplicative factor being a function of the dynamic compensation factor to obtain a plurality of reduced third bank angles, and calculating a final bank angle bias estimate based on a sum of the plurality of reduced third bank angles.

摘要： A hybrid vehicle and method of control are disclosed wherein the ratio of engine speed to vehicle speed varies continuously in some operating modes and is controlled to simulate a discrete ratio transmission in other operating modes. The disclosure specifies the method of controlling the engine speed and the combined output torque of the engine and at least one traction motor in each of the operating modes. Transitions among operating modes occur in response to driver movement of a shift lever, driver operation of shift selectors, and changes in vehicle speed.

摘要： A system and method for controlling a hybrid electric vehicle powertrain having an engine defining one power source, and a traction motor and electrical storage device defining another power source include inhibiting a stopping and a starting of the engine based upon an unintended tip-out event and an unintended tip-in event, respectively. The total power demand and the available electric power are determined. The total power demand is filtered. The engine is prevented from being pulled-up or pulled-down based upon a difference between the total power demand and the filtered power demand being exceeding a threshold. However, if the difference exceeds the threshold, and if the available electric power exceeds the total power demand, then the engine is permitted to pull-up or pull-down.

摘要： A hybrid vehicle and method of control are disclosed wherein the ratio of engine speed to vehicle speed varies continuously in some operating conditions and is controlled to be one of a finite number of preselected ratios in other operating conditions. The transition from continuously variable mode to discrete ratio mode includes selecting a virtual gear number and increasing the engine speed to the corresponding ratio to vehicle speed. Once in a discrete ratio mode, the virtual gear number can vary automatically in response to changes in vehicle speed or in response to driver activation of shift selectors.

摘要： An independent wheel torque control algorithm is disclosed for controlling motor torques applied to individual electric motors coupled to vehicle wheels in an electric vehicle. In a first range of vehicle states, vehicle steerability is favored so that the operator of the vehicle suffers little or no longitudinal propulsion loss while steering is enhanced. In a second range of vehicle states, vehicle stability is favored. According to embodiments of the disclosure, a desired yaw moment is computed and then may be reduced in magnitude due to system limitations, electrical or friction limits, which prevents the desired yaw moment from being fully realized.

摘要： A system for distributing propulsion to front and rear axles of a vehicle includes: a front axle motor coupled to the front axle and a rear axle motor coupled to the rear axle. An electronic control unit (ECU) electronically coupled to the motors commands the rear axle motor to increase torque supplied to the rear axle during understeer and commands the front axle motor to increase torque supplied to the front axle during oversteer. A method to distribute propulsion to front and rear axles of a vehicle includes estimating actual yaw rate, estimating desired yaw rate, providing electrical energy to the front axle motor during oversteer, and providing electrical energy to the rear axle motor during understeer. Additionally, electrical energy may be extracted from the rear axle motor during oversteer and electrical energy may be extracted from the front axle motor during understeer.

摘要： A method and system for providing a dynamic torque band for hybrid electric vehicle (HEV) transient management includes determining a torque band indicative of an engine torque operation region representing efficient operation of the powertrain across a range of engine speeds. An engine torque command based on an actual speed of the engine is generated. The engine torque command is outputted to the engine if the engine torque command is within the torque band. The engine torque command is modified to be within the torque band if the engine torque command is out of the torque band and the modified engine torque command is outputted to the engine.
