Abstract: Provided is a braking control device configured to apply auxiliary braking force only as needed, for example, when a travel path of a vehicle includes a curve such as a blind corner, and configured to apply the auxiliary braking force without causing a driver of the vehicle to feel uneasy about operation. The braking control device calculates target braking force based on reference braking force and input braking force information (a driver-input braking force converted value), calculates, based on the target braking force, the auxiliary braking force for reducing uneasiness (performing a process to reduce uneasiness) felt by the driver about the braking operation, and then calculates final target braking force by using the auxiliary braking force (by adding the auxiliary braking force to the driver-input braking force converted value).

Abstract: A support structure for a vehicle includes: a body portion (22); a damper attachment portion (24); a tie-rod attachment portion (26); and a lower arm attachment portion (28). The vehicle supporting structure (20) has a first rib (32) that connects the damper attachment portion (24) with the tie-rod attachment portion (26), a second rib (34) that connects the tie-rod attachment portion (26) and the lower arm attachment portion (28), and a third rib (36) that connects the first rib with the second rib. The first rib is inclined to have a height that gradually decreases from the damper attachment portion toward the tie-rod attachment portion, forming a first inclined portion (32a) and a first thinned portion (32b). The third rib is inclined to have a height that gradually decreases from the second rib toward the first rib, forming a second inclined portion (36a) and a second thinned portion (36b).

Abstract: There is provided a front structure of a handlebar vehicle that allows clutch and brake operations to be easily performed with one hand of the rider, a clutch lever that activates a clutch device and a brake lever of a brake device that activates a rear-wheel brake being arranged around a grip provided at a side-end part of a steering handlebar. The brake device is provided with a hydraulic master cylinder provided with a cylinder hole that accommodates a piston, and a brake lever that activates the piston. A clutch grip operation part of the clutch lever and a brake grip operation part of the brake lever extend along the grip and are able to rotate in the same rotation direction, and the clutch lever is disposed higher in the body of the vehicle than the brake lever.

Abstract: A steering device has a rib formed on a housing. The rib includes a first rib and a second rib intersecting with the first rib. When, in the two ends of the first rib, an end close to an intersection portion is defined as one end, the first rib includes a brittle portion which has reduced strength in comparison with those of the other portions and which is provided between the intersection portion and the one end.

Abstract: A rotation speed or a rotation time of a crankshaft at a certain angle is calculated on a basis of a change in a detection signal of a sensor of the crankshaft. Then, when a combustion cylinder is switched, information on the rotation speed or the rotation time for at least two combustion cycles is obtained, and a combustion phase is calculated on the basis of the rotation speed or the rotation time. Accordingly, by using the that measures rotation of the crankshaft, it becomes possible to detect a combustion state of the internal combustion engine with high accuracy.

Abstract: Provided is a hybrid vehicle control device excellent in quietness while suppressing knocking within an allowable limit. The hybrid vehicle control device of an aspect of the invention is a hybrid vehicle control device that controls a hybrid vehicle including a motor that drives wheels, a generator that supplies electric power to the motor, and an engine configured by an internal combustion engine that drives the generator, and includes a control unit that calculates a knock index value indicating a knock degree of the engine at an engine operating point represented by a relationship between an engine rotational speed and an engine torque, and controls the engine rotational speed and the engine torque based on the knock index value. As the knock index value decreases, the control unit sets the target engine rotation speed to be lower and the target engine torque to be higher in the target power generation amount.

Abstract: According to an aspect of the present invention, a vehicle control device, a vehicle control method, and a vehicle control system calculates, while retaining a part of a first target trajectory calculated at a first time for calculating a target trajectory along which a vehicle is to travel, a second target trajectory at a second time which is a next calculation timing of a target trajectory after a calculation cycle from the first time. The retained part of the first target trajectory includes a section corresponding to a distance to be traveled by the vehicle during a time from the first time to the second time, and a first target position set on the first target trajectory. This makes it possible to prevent occurrence of an unexpected vehicle behavior while ensuring the control performance for tracking the target trajectory.
