Systems and methods for detecting and controlling a fluid consumption detection warning

Systems and methods for providing vehicle condition indicators are provided. The method for controlling the vehicle includes receiving sensor information from a plurality of sensors associated with the vehicle. The sensor information includes throttle values and lateral acceleration values. The method also includes analyzing the throttle values for a plurality of points in time to determine whether to activate an aggressive throttle flag. The method further includes analyzing the lateral acceleration values for the plurality of points in time to determine whether to activate an aggressive lateral acceleration flag. In addition, the method includes activating a fluid consumption detection enable flag when the aggressive throttle flag and the aggressive lateral acceleration flag are both active.

Camera based vehicle start-stop feature

A method of vehicular control includes providing a camera and a control at a vehicle. Image data captured by the camera is processed at the control to determine presence of a stopping area ahead of the vehicle and being approached by the vehicle as the vehicle is maneuvered along the road. Responsive to determination of presence of the stopping area, and responsive to determination that the driver releases the accelerator pedal of the vehicle, the operating capacity of the vehicle engine is reduced so that the engine operates at reduced capacity as the vehicle moves toward and stops, via the driver applying the brake pedal of the vehicle, at the determined stopping area. After stopping the vehicle, the control determines if a hazard is present in the field of view of the camera and restores the operating capacity of the engine its normal operating capacity if no hazard is present.

Vehicular brake system

A hydraulic oil resupply device (40) is provided between first accumulators (15F, 15R) in a manual braking operation circuit (11) and a second accumulator (25) in an automatic brake circuit (24). The hydraulic oil resupply device (40) resupplies hydraulic oil accumulated in the second accumulator (25) to the first accumulators (15F, 15R) at the operating of a manual braking operation by an operator. This configuration can suppress a rising speed of a brake pressure at the manual operation braking from being slow. Accordingly, in a vehicular brake system, it is possible to enhance a braking capability by the manual braking operation and improve the reliability.
