Vehicle control system

A vehicle control system is provided to maintain an SOC level of the battery during autonomous operation of the vehicle. The control system is applied to a vehicle that can be operated autonomously by controlling an engine, a motor, a steering system, a brake system etc. autonomously by a controller, and the vehicle is allowed to coast by manipulating a clutch. During autonomous operation of the vehicle, a first coasting mode in which the engine is stopped and the clutch is disengaged is selected if the SOC level is higher than a threshold level, and a second coasting mode in which the engine is activated and the clutch is disengaged is selected if the SOC level is lower than the threshold level.

20230159030 · 2023-05-25 ·

A vehicular driver assist system includes a forward-viewing camera disposed at and viewing through a windshield of a vehicle. The vehicular driver assist system sets an initial vehicle soft lock speed when speed of the vehicle reaches an initial threshold speed of travel. With the initial vehicle soft lock speed set and with the vehicle speed exceeding the initial vehicle soft lock speed, the system maintains the vehicle speed at the initial vehicle soft lock speed when the vehicle speed reduces to the initial vehicle soft lock speed by coasting. When speed of the vehicle increases by a multiple of a vehicle speed increment above the initial vehicle soft lock speed, the system sets an increased vehicle soft lock speed and maintains the vehicle speed at the increased vehicle soft lock speed when the vehicle speed reduces to the increased vehicle soft lock speed by coasting.

Predictive adaptive cruise control

Systems and methods for predictive adaptive cruise control of a plurality of vehicles traveling in succession. A system engages in a vehicle-to-vehicle communication session with one or more vehicles of the plurality of vehicles. During the communication session, terrain information is obtained and first speed trajectory information is determined for an upcoming segment of road. Second speed trajectory information is received from a first adjacent vehicle of the plurality of vehicles. Third speed trajectory information is generated based on the second speed trajectory information received and the terrain information. The operation of the vehicle is controlled during the upcoming segment according to the third speed trajectory information.

VEHICLE

A vehicle includes a controller configured to switch between a constant speed traveling mode in which a vehicle speed is held constant and an inertial traveling mode in which a prime mover is stopped or in an idling state, and a clutch apparatus configured to connect and disconnect power transmission between the prime mover and an output target, and the controller controls the clutch apparatus and decreases a clutch capacity so as to transit to the inertial traveling mode when detected that the vehicle is traveling on a downhill road during the constant speed traveling mode, and the controller controls the clutch apparatus and increases the clutch capacity so as to transit to the constant speed traveling mode when detected that the vehicle traveling on the downhill road has terminated.

METHOD AND CONTROL SYSTEM FOR GENERATING AN OPTIMAL DRIVING PROFILE FOR VEHICLES PROVIDED WITH ELECTRIC PROPULSION

An optimal driving profile is generated for vehicles provided with electric propulsion, by providing a sequence of consecutive time intervals until an arrival time and providing a plurality of accelerations that the vehicle can hypothetically take in each of the time intervals; by applying laws of uniformly accelerated motion for each of the accelerations and for each of the time intervals, hypothetical future points along the route are generated, starting from the current position and speed of the vehicle; for each of the time intervals, before analysing the subsequent time interval, it is checked whether the generated points meet all the predefined constraints; if the check has a negative outcome, the point being checked is eliminated from the plausible hypotheses; driving profiles are obtained, each defined by a respective sequence of remaining points; from among said driving profiles, the one requiring a lowest overall energy to be executed is selected.

A control method and a control device are provided for autonomously controlling a host vehicle when turning across an oncoming lane at an intersection with a signal light being green. A determination is made as to whether or not the host vehicle can make a right or left turn while a signal light is still green at a time of the right or left turn, either while the host vehicle in the left lane is waiting in a row of vehicles to make the right turn or while the host vehicle traveling in the right lane is waiting in a row of vehicles to make the left turn at an intersection during travel under autonomous driving. The host vehicle then creeps forward to a start position for starting at a next time the signal light is green upon determining the right or left turn cannot be made.
