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.

An apparatus for shift control in a vehicle includes: a transmission; an acceleration apparatus; and a control circuit electrically connected with the transmission and the acceleration apparatus. The control circuit shifts the transmission from a drive state to a neutral state when an activation condition for coasting is satisfied during travel of the vehicle, and corrects an oil pressure for release of a clutch in the transmission at the time of a kickdown shift, when a driver's input for kickdown is detected through the acceleration apparatus during the coasting.

A drive control system for a motor vehicle operated by electric motor has a drive position selector device and an electronic control unit which is connected to the drive position selector. The drive control system is configured in such a way that when a first alternative automatic drive position is selected a comparatively high, not freely selectable recuperation level can be predefined and crawl mode is deactivated, and when a second alternative automatic drive position is selected at least one constant recuperation level or a sailing mode can be predefined and crawl mode is activated.

An apparatus configured for controlling starting of engine may include a clutch pedal including an ignition lock switch, a starter, a status detecting unit, an electronic clutch mounted between the engine and a transmission, a clutch controller configured to control coupling and releasing of the electronic clutch, check status of the electronic clutch and generate a clutch status data, and a vehicle controller configured to enter coasting running mode based on the vehicle status data, and, during the coasting running mode, operate the starter and restart the engine based on the clutch status data provided from the clutch controller and a switch status data of the ignition lock switch when a position value of an acceleration pedal included in the vehicle status data is equal to or greater than an acceleration reference value.

A controller determines a target rotation speed of an engine from an operation amount of an accelerator operating member. The controller determines whether a vehicle is in coasting deceleration. The controller decreases a differential pressure between a first circuit and a second circuit of a hydraulic circuit according to a deviation between an actual rotation speed of the engine and the target rotation speed, or the operation amount of the accelerator operating member when the vehicle is in the coasting deceleration.

A system, method, and apparatus include a controller structured to predict a change in speed of a vehicle in advance of upcoming terrain and inhibit a coasting event if the speed exceeds a limit. In one form a velocity of the vehicle is predicted using a physics based model of the vehicle within a look ahead window in front of a vehicle. Such a look ahead window can be distance or time based. In another, 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. The threshold is a function of road grade, and permits a larger deviation from set speed at low grade than at high grade. The function can be based on road grade and vehicle weight.

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 system for controlling torque of a vehicle, such as an eco-friendly vehicle, can improve steering control performance. The system includes a first controller configured to change coast regeneration torque of the vehicle according to whether wheel lock of the vehicle has occurred and whether the vehicle is steerable.

The braking force control device detects an impossible state where one or some of the actuators are temporarily unable to generate a negative driving force, and a predictive state where one or some of the actuators are predicted to become unable to generate a negative driving force. Every time the coasting state occurs before establishment of the impossible state and after establishment of the predictive state, the braking force control device gradually increases the negative driving force generated by the corresponding one or ones of the actuators. Even when the coasting state occurs in the impossible state, the braking force control device does not cause the corresponding one or ones of the actuators to generate a driving force. Every time the coasting state occurs after the impossible state, the braking force control device gradually decreases the negative driving force generated by the corresponding one or ones of the actuators.

Disclosed are a vehicle and a method of providing fuel consumption information thereof in which the influence of driver's pedal operation on actual fuel consumption, including a latent distance to empty (DTE), due to variation in kinetic energy of the vehicle may be displayed. The method includes detecting whether or not one of an accelerator pedal and a brake pedal is operated, determining guidance fuel consumption based on a change in an available coasting distance according to a change in a vehicle speed due to operation of the one of the accelerator pedal and the brake pedal, which is detected, and outputting the determined guidance fuel consumption.
