A control method for a mild type hybrid electric vehicle is provided. The method determining whether a coasting condition is satisfied and initiating coasting when the coasting condition is satisfied. A reacceleration intention is then detected and a torque of a mild hybrid starter & generator (MHSG) is increased in response thereto. A revolutions per minute (RPM) of the MHSG is compared with a RPM of an engine an engagement of the MHSG with the engine is attempted when the RPM of the MHSG corresponds to the RPM of the engine. The RPM of the MHSG is then synchronized with the RPM of the engine. When the MHSG is successfully engaged with the engine, the torque of the MHSG is increased to inject a fuel to the engine.

A control apparatus for a vehicle that includes an engine includes an electric generator, a throttle valve, an electric generator control unit, and a throttle control unit. The electric generator is configured to be coupled to the engine. The throttle valve is configured to control an amount of intake air of the engine. The electric generator control unit is configured to allow the electric generator to perform regenerative power-generation on decelerated travel of the vehicle. The throttle control unit is configured to control the throttle valve openwise on the decelerated travel. The electric generator control unit is configured to cause an increase in power-generation torque of the electric generator, upon a switchover of the engine from a fuel cut state to a fuel injection state on the decelerated travel.

A system for a vehicle including a controller structured to communicate with a transmission and an engine of a vehicle, and additionally structured to: receive at least one of vehicle operation data, route data, or dynamic data during operation of the vehicle; determine that the vehicle is in a coasting state based on the at least one of the vehicle operation data, the route data, or the dynamic data; provide a command to at least one of the engine and the transmission to maintain the coasting state for the vehicle; and determine an end of the coasting state based on the at least one of the vehicle operation data, the route data, or the dynamic data.

Systems and methods of selective driver coaching are provided. Driver coaching systems learn the characteristics of a deceleration event. With the goal of increasing recouped energy while operating a hybrid electric vehicle (HEV), driver coaching systems predict when the HEV can begin coasting at the start of the deceleration event. In this way, the amount of time during which regenerative braking can be applied may be increased. Coaching cues are provided to the driver so that the HEV can be operated in way that achieves the goal of increasing recouped energy. However, engaging in excessive regenerative breaking can negate its advantages if the amount needed to reaccelerate the HEV to a cruising/steady speed is too great. Selective driver coaching provides coaching cues only if the operating efficiency of the HEV exceeds the operating efficiency of the HEV when controlled by the driver without coaching cues.

A vehicle control device is for a vehicle having a drive source, and an automatic transmission connected to the drive source, the automatic transmission having an engagement element for disconnecting/connecting transmission of a driving force and a variator placed further upstream than the engagement element. The vehicle control device includes first and second control units. The first control unit is configured to execute sailing stop control to stop the drive source and to put the automatic transmission into a neutral state when a sailing stop condition is established. The second control unit is configured to start the drive source and to implement downshifting of the variator when a size of a deceleration level is a prescribed value or greater when the sailing stop control is cancelled due to a prescribed sailing stop cancellation condition among sailing stop cancellation conditions being established, and to engage the engagement element after the downshifting.

A system, method, and apparatus includes management of coasting during operation of a vehicle. Speed of a vehicle is monitored during a coasting event and is compared against a threshold to determine whether to remain coasting or re-engage an engine to a driveline. If instantaneous speed exceeds the threshold, predicted speed can be used to determine whether to permit short duration excursions, or to re-engage the engine to the driveline. These techniques can be used whether the vehicle is slowing down below a threshold or speeding up above a threshold.

A control method for an autonomous vehicle is used in an autonomous vehicle including an engine, and a controller that controls an operation of the engine. In the control method, required driving force is set in accordance with an intervehicular distance between an own vehicle and a preceding vehicle when there is the preceding vehicle in front of the own vehicle. Also, when there is the preceding vehicle, a behavior of the preceding vehicle is predicted from a situation in front of the preceding vehicle. Further, when there is the preceding vehicle, sailing stop is executed based on the required driving force and the predicted behavior of the preceding vehicle. The sailing stop causes the engine to stop automatically while the own vehicle is traveling at vehicle speed equal to or higher than given vehicle speed.

A hybrid electric vehicle is capable of maximizing energy efficiency during platooning, and a platooning control method is carried out on the hybrid electric vehicle. The method includes acquiring acceleration information and deceleration information of each of a plurality of vehicles traveling in a platoon form for platooning so as to realize a pulse-and-gliding traveling mode, determining a traveling order of the vehicles during the platooning based on the acceleration information, and determining a time at which to start a glide phase of a following vehicle in the determined traveling order based on a time at which a glide phase of a preceding vehicle starts using the acceleration information and the deceleration information.

A vehicle control device executes a traveling control that controls traveling of an own vehicle to enable the own vehicle to follow a preceding vehicle traveling in front of the own vehicle. The vehicle control device includes: an environment prediction unit that predicts whether an adverse-effect change has occurred in a surrounding environment around the own vehicle, the adverse-effect change being likely to have an adverse effect on a fuel economy of the own vehicle; and an acceleration control unit configured to execute a prediction control that enables an acceleration of the own vehicle to be limited when the environment prediction unit predicts that the adverse-effect change has occurred in the surrounding environment.

A method for operating a motor vehicle, the motor vehicle including a prime mover (1), a transmission (2), and a driven end (3), wherein the transmission (2) is an automatic or automated transmission and is connected between the prime mover (1) and the driven end (3). The method includes activating a sailing mode of the motor vehicle depending on at least one operating condition of the motor vehicle; performing a gear select interlock in the transmission (2), while maintaining the sailing mode, when the sailing mode is active; and deactivating the sailing mode is subsequently depending on at least one operating condition of the motor vehicle. The gear select interlock is implemented in the transmission (2) depending on a rotational speed of the prime mover (1) and depending on synchronous speeds of the gears of the transmission (2).
