20230250784 · 2023-08-10 ·

Systems and methods for improving operation of a vehicle are presented. In one example, a controller may respond to a presence or absence of a prediction of an increase in vehicle speed during a look ahead window. The controller may inhibit or allow automatic engine stopping in response to the presence or absence of the prediction of the increase in vehicle speed during the look ahead window.

Methods and systems for controlling engine idle-stop

Methods and systems are provided for controlling an engine idle-stop based on upcoming traffic and road conditions. In one example, a method may include receiving data including traffic information and road characteristics immediately ahead of a vehicle from one or more remote sources, and adjusting one or more vehicle thresholds based on the received data. A duration of a prospective engine idle-stop may be estimated based on the received data and an engine idle-stop may be initiated based on the duration of the prospective engine idle-stop and the adjusted one or more vehicle threshold.

Start-stop control apparatus

Provided is a start-stop control apparatus to be mounted in a vehicle including an engine, a starter motor configured to restart the engine, and an auxiliary battery configured to supply electric power to the starter motor. The start-stop control apparatus includes a stop processing unit and an engine measuring unit. The stop processing unit stops idling of the engine while the vehicle is being stopped. The engine measuring unit measures an internal loss of the engine. The stop processing unit determines whether to stop the idling of the engine on the basis of the internal loss measured by the engine measuring unit and the state of charge of the auxiliary battery.

A motor vehicle stop/start control system for controlling at least a portion of a powertrain of a vehicle, the system being configured to: receive speed information indicative of vehicle speed; and receive brake information indicative that a braking system has been activated to apply brake torque; wherein the control system is further configured to cause an engine of the motor vehicle to be switched off when a first set of predetermined conditions are met, the first set of conditions including the conditions that the brake information indicates that the braking system is active and the speed information indicates that vehicle speed is a below a predetermined engine-off speed, the engine-off speed being determined by the control system at least in part by reference to information received by the control system.

System and method for controlling remote starting of vehicle

A system and method for controlling the remote starting of a vehicle are provided to determine whether the remote starting is possible by comparing a parking lever operating force measured by a sensor with a reference parking lever operating force corrected in consideration of the durability degradation of a parking system. The method includes sensing a driving distance of the vehicle, operating times of a parking lever, a road inclination, and a parking lever operating force, when the vehicle is parked. Whether the remote starting is possible is determined by comparing a magnitude of the parking lever operating force with a magnitude of a reference parking lever operating force.

CONTROL SYSTEM OF HYBRID VEHICLE

When a vehicle is in a traveling state having a low necessity to quickly increase required traveling torque, high-rotational-speed engine starting unit that reduces an emission amount of particulate matter emitted during engine starting starts the engine. Since quick torque response is not required when the vehicle is in the traveling state having the low necessity to quickly increase the required traveling torque, the high-rotational-speed engine starting unit starts the engine, so that increase of the emission amount of particulate matter emitted during engine starting can be curbed.

CONTROL DEVICE, CONTROL METHOD, AND VEHICLE

An electronic control unit is a control device for controlling a vehicle including a vehicle speed sensor. The electronic control unit is configured to identify a section from start to stop of the vehicle using a vehicle speed detected by the vehicle speed sensor, determine whether the number of times of a low-speed section is more than a prescribed number of times, the low-speed section being the identified section where a representative value of the vehicle speed is less than a prescribed speed, and determine that the vehicle is in a specific situation where low-speed travel is inevitable, when it is determined that the number of times of the low-speed section is more than the prescribed number of times.

AUTOMATIC STOP/RESTART SYSTEM FOR INTERNAL COMBUSTION ENGINE
20210293188 · 2021-09-23 · ·

A vehicle equipped with an automatic stop/restart system for an internal combustion engine includes a hydraulic continuously variable transmission and a parking mechanism. The continuously variable transmission changes power of the internal combustion engine using hydraulic pressure boosted by rotational driving force of the internal combustion engine. The parking mechanism holds the vehicle stationary by locking, with a locking member, the rotation of a power transmitting member between the internal combustion engine and driving wheels when a shift position is in a parking range. In an automatic stop state of the internal combustion engine, when the shift position is in the parking range and brakes are turned off, an electronic control unit executes restart if an inclination angle of the vehicle is greater than or equal to a predetermined value, and maintains the automatic stop state if the inclination angle is smaller than the predetermined value.
