Abstract: A travel control device repeats a burn control that accelerates a vehicle at a target acceleration until speed of the vehicle reaches an upper limit speed of a vehicle speed range and a coasting control that makes the vehicle travel by means of inertia until the speed of the vehicle reaches a lower limit speed of the vehicle speed range. Further, a vehicle speed width that is a width of the vehicle speed range and the target acceleration are changed based on calculated travel resistance.

Abstract: A controller includes a SOC prediction unit to predict a SOC, based on a predicted result of a road grade and a vehicle speed in a scheduled travel route, and a discharge control unit to execute a discharge increasing control to previously increase a discharge quantity of the battery to prevent the battery from becoming in a saturation state based on a predicted SOC, when the battery becomes in the saturation state. The discharge control unit includes a first mode to execute an assist discharge increasing control in an assist travel, and a second mode to execute an EV discharge increasing control by decreasing the vehicle speed and by increasing an opportunity of an EV travel, as the discharge increasing control. When the EV discharge increasing control can be executed, the EV discharge increasing control is executed with priority relative to the assist discharge increasing control.

Abstract: A vehicle control device that includes a search unit that searches, based on geographic information to be supplied from a navigation device, for a deceleration start position before a downhill that is suited to regeneration by a motor; and a charge level control unit that performs, when a vehicle reaches the deceleration start position, deceleration control for reducing a charge level of a battery by reducing a vehicle speed. When the charge level control unit performs the deceleration control, the vehicle speed is reduced by reducing a driving force of the vehicle to a level at which only motor output is used as the driving force.

Abstract: A vehicle control device includes an engine, and a motor that is driven by power to be supplied from a battery, the vehicle control device controlling a vehicle that uses at least one of engine output and motor output as a driving force. The vehicle control device includes a regeneration control and a downhill-acceleration control unit. The regeneration control unit causes the motor to perform regeneration on a downhill. The downhill-acceleration control unit performs downhill acceleration control for causing, in a specific zone on the downhill, the vehicle to travel at increased speed without allowing the vehicle to use the engine output as drive output, and without causing the motor to perform the regeneration.

Abstract: A controller is applied to a vehicle including an engine (11) and a motor generator (12 and 13) as power sources of the vehicle and a battery (20) that transfers power with the motor generator. The controller charges the battery with a regeneration power that is a power regenerated by the motor generator when the vehicle is decelerated. The controller includes a SOC prediction unit (39, 50 and 205) to predict a SOC indicating a remaining capacity of the battery in a scheduled travel route of the vehicle, based on a predicted result of a road grade and a vehicle speed in the scheduled travel route, a discharge control unit (39, 52, 206, 208 and 301 to 303) to execute a discharge increasing control to previously increase a discharge quantity of the battery to prevent the battery from becoming in a saturation state based on a predicted SOC that is the SOC predicted by the SOC prediction unit, when the discharge control unit determines that the battery becomes in the saturation state where the battery cannot be charged with the regeneration power based on the predicted SOC, a determination unit (39 and 105 to 109) to determine whether a behavior of the predicted SOC shifts from a behavior of an actual SOC or determine whether a SOC shift factor occurs, after a start of the discharge increasing control, where the SOC shift factor is a vehicle control or an environment change that predicts the behavior of the predicted SOC shifts from the behavior of the actual SOC, and a correction unit (39, 110, 201 to 209 and 301 to 303) to correct the discharge increasing control by executing a prediction of the SOC in the scheduled travel route again, when the determination unit determines that the behavior of the predicted SOC shifts from the behavior of the actual SOC or determines that the SOC shift factor occurs.

Abstract: A travel control apparatus is provided with: a speed controller that controls speed of a vehicle having an internal combustion engine; and a determination part that determines an emission deterioration state of the internal combustion engine. The speed controller is configured to execute burn-and-coast control that repeatedly executes burn control in which the vehicle is accelerated by driving force of the internal combustion engine, and coasting control in which the vehicle is driven by inertia, by stopping the generation of the driving force or rotation of the internal combustion engine. The speed controller is configured to execute emission suppression control that suppresses emissions by adjusting the burn-and-coast control when the emission deterioration state of the internal combustion engine is determined by the determination part.
