A method and system for determining a maximum cornering braking threshold for a motorcycle includes determining an absolute lean angle with respect to horizontal and a relative lean angle for the motorcycle relative to a road surface. The maximum cornering braking threshold is determined from at least the absolute lean angle and the relative lean angle. The maximum cornering braking threshold is used to provide stability during motorcycle cornering. A multi-dimensional look-up table stores different maximum cornering braking thresholds that correspond to different combinations of absolute lean angles and relative lean angles. The relative lean angle is determined by processing video data from a video sensor. Values for additional conditions, such as motorcycle speed, wheel slip coefficient, steering angle, mue and type of road way are stored in the multi-dimensional look-up table to assist in determining the maximum cornering braking threshold.

A vehicle stop maintaining system comprises an automatic transmission, an automatic stop-restart mechanism for automatically stopping and restarting an engine, a foot brake mechanism for braking vehicle wheels through hydraulic brake mechanisms, a brake force control mechanism having a pressurizer that increases hydraulic brake pressure applied to the hydraulic brake mechanisms, and for braking the wheels by controlling the pressurizer independently from brake pedal depression, a controller configured to maintain a vehicle stopped state by operating the automatic stop-restart mechanism to stop the engine and operating the brake force control mechanism to keep initial hydraulic brake pressure according to the brake pedal depression, and a drive force state determining module for determining a drive force stabilized timing. The controller operates the automatic stop-restart mechanism to restart the engine and operates the brake force control mechanism to release the initial hydraulic brake pressure when accelerator pedal depression is detected.

A vehicle stop maintaining system comprises a foot brake mechanism for braking vehicle wheels by applying hydraulic brake pressure to hydraulic brake mechanisms according to a depression of a brake pedal, a brake force control mechanism having a pressurizer that increases hydraulic brake pressure to be applied to the hydraulic brake mechanisms, braking the wheels by controlling the pressurizer independently from the depression of the brake pedal, and a controller for executing, when the vehicle is detected to be in a stopped state, a first stop mode in which the brake force control mechanism is operated to maintain the stopped state. The system includes a gear position detector for detecting a position of a gear shift lever of the vehicle. When a vehicle driver intentionally controls the gear shift lever to a reverse position in the first stop mode, the controller cancels the first stop mode.

A vehicle stop maintaining system is provided, which includes a foot brake mechanism for braking vehicle wheels by applying hydraulic brake pressure according to brake pedal depression, a brake force control mechanism for braking the wheels by controlling a pressurizer, an electric parking brake mechanism for braking the wheels by operating an electric brake mechanism, and a controller comprising a processor for entering a first stop mode when a vehicle stopped state is detected. The processor executes a first determining module for determining existence of an interruptive factor, and a second determining module for determining a failure of the electric parking brake mechanism. If the interruptive factor exists, the controller executes a second stop mode. If the electric parking brake mechanism is determined as failed under the second stop mode, the controller operates a notification device for issuing a notification to a vehicle driver.

A driver assistance system is presented, including an event detector which comprises a set of rules defining a surprising event based on signals reflecting a vehicle operator input signals from an object detection sensor. An event data file generator is configured to generate an event data file according to rules comprised in the event detector, the event data file comprising a video signal received from a camera, a signal from at least one dynamic vehicle sensor, and target object information received from the object detection sensor. The event data file generator is further configured to initiate data file generation responsive to a surprising event being detected by the event generator, and wherein the contents of the data file are specified by the rules comprised in the event detector. In this way, surprising events may be collected and analyzed off-board in order to generate updates for the driver assistance system.
