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 control system for an electrified vehicle includes a friction brake system configured to apply a frictional force to a driveline system of the electrified vehicle to decelerate the electrified vehicle and a controller configured to detect an upcoming downhill grade and, in response to detecting the upcoming downhill grade, predict a thermal parameter of the friction brake system during the upcoming downhill grade and control enablement/disablement of a power dissipation mode of the electrified vehicle when the predicted thermal parameter exceeds a thermal parameter threshold corresponding to overheating of the friction brake system, wherein the power dissipation mode includes intentionally dissipating at least some of the electrified vehicle's potential energy using a set of power dissipation components of the electrified vehicle.

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.

Provided is a vehicle control device 21 capable of automatically starting electric traveling with high quietness in a case where a hybrid vehicle approaches a base without a driver performing a switching operation or setting a destination with respect to a navigation device when the hybrid vehicle travels near the base. The vehicle control device 21 is mounted on a vehicle 100 which switches between a first traveling state in which the vehicle 100 is driven by transmitting a driving force of an electric motor 107 by power supply from a battery 105 to drive wheels 109 and a second traveling state in which the vehicle 100 is driven with at least operation of an engine 102. The vehicle control device 21 includes a determination value storage unit 27 which allocates and stores, for each of a plurality of predetermined points, a determination value obtained based on a battery consumption amount required for the vehicle 100 to travel in the first traveling state from a predetermined point to the bases 31, 31A, and 31B and a target battery remaining amount at the time of arrival at the bases 31, 31A, and 31B, and a traveling state determination unit 28 which starts traveling in the first traveling state in a case where a current battery charge amount of the vehicle 100 exceeds a determination value corresponding to a current point of the vehicle 100.

A controller for a vehicle is provided. An air supply passage is connected to a portion upstream of a filter in an exhaust passage. An air supplying process supplies air to the filter through an air supply passage by driving an air pump. An oxygen supplying process supplies oxygen to the filter through the exhaust passage, the oxygen having been passed through a combustion chamber of an internal combustion engine. A reducing process sets an air supply amount per unit time in the air supplying process obtained when the oxygen supplying process and the air supplying process are simultaneously executed to be lower than the air supply amount per unit time in the air supplying process obtained when the oxygen supplying process and the air supplying process are not simultaneously executed.

In some implementations, a plug-in series hybrid electric vehicle may include an engine, a motor/generator (MG), a traction motor, an energy storage device, and a controller. The controller is coupled to the engine and the MG to control operation of the engine and the MG such that a state-of-charge (SOC) of the energy storage device tracks a dynamic reference SOC profile during a trip and an average engine power (AEP) is maintained above a threshold. In some instances, maintaining AEP above a threshold supports emission control of the vehicle.

The driving/braking force distribution control unit performs a control of an output allocation ratio between the front-wheel longitudinal force generator and the rear-wheel longitudinal force generator based on a target value of an additional yaw moment, a change rate of a tire lateral force of a front wheel to a slip ratio of the front wheel, and a change rate of a tire lateral force of a rear wheel to a slip ratio of the rear wheel.
