An eco-friendly vehicle and a launch control method for an eco-friendly vehicle reduces an unpleasant secondary launch effect based on a gear alignment state of a transmission in a specific situation. The launch control method includes: determining a first condition for enabling a preset stop control when the first condition is satisfied; turning off a control for generating a creep torque of a motor when a brake is released; controlling a transmission in an open state and enabling the control for generating the creep torque; and when a second condition for revolutions per minute (RPM) of the motor is satisfied, controlling the transmission in a lock state through a slip state.

A method for controlling a sudden unintended acceleration due to misoperation of an engine in a power split type hybrid electric vehicle (HEV) system, the method including when a determination is made that a delta revolution per minute (RPM) of an engine is out of a predetermined criterion, determining that an operating point of the engine does not move along a profile defined according to a target operating point of the engine and the sudden unintended acceleration is possible. The delta RPM is a difference of value between a current RPM of the engine and a profile RPM of the engine required to move to the target operating point of the engine from a current operating point of the engine.

Operation of the first, second and transmission clutches in coordination with electric motor and engine operation provides multiple operating modes while minimizing operator disturbance during transitions between engine deactivated and activated states.

The purpose of the present invention is to improve fuel efficiency during coasting by calculating, with high accuracy, travel resistance during coasting. This vehicle control device comprises: a first travel resistance acquisition unit that acquires a first travel resistance, which is determined on the basis of road information or external information; and a second travel resistance acquisition unit that acquires a second travel resistance, which is determined on the basis of the result of actual traveling of the vehicle. This vehicle control device determines the content of coasting travel control during traveling of the vehicle on the basis of the result of a comparison of the first travel resistance and the second travel resistance in a predetermined zone where the vehicle has actually traveled.

A system, comprising a first computer that includes a processor and a memory. The memory stores instructions executable by the processor to input an expected control input to a second computer, and then, to determine a response resulting from the expected control input. The memory stores instructions to determine a compensated control input based on the expected control input and the response, and to input the compensated control input to the second computer to achieve the expected control input. The second computer is provided to actuate a vehicle component to achieve the expected control input.

A through the road (TTR) hybridization strategy is proposed to facilitate introduction of hybrid electric vehicle technology in a significant portion of current and expected trucking fleets. In some cases, the technologies can be retrofitted onto an existing vehicle (e.g., a trailer, a tractor-trailer configuration, etc.). In some cases, the technologies can be built into new vehicles. In some cases, one vehicle may be built or retrofitted to operate in tandem with another and provide the hybridization benefits contemplated herein. By supplementing motive forces delivered through a primary drivetrain and fuel-fed engine with supplemental torque delivered at one or more electrically-powered drive axles, improvements in overall fuel efficiency and performance may be delivered, typically without significant redesign of existing components and systems that have been proven in the trucking industry.
