摘要： A steering actuator is prevented from generating excess steering torque that gives an uncomfortable feeling to a driver who is holding a steering wheel when a collision between a vehicle and an oncoming vehicle is avoided by automatic steering by the actuator. When there is a possibility of a collision between the vehicle and an oncoming vehicle, the collision with the oncoming vehicle is avoided by supplying a lateral movement control current having a sinusoidal shape to the actuator of an electric power steering device to move the vehicle laterally. The yaw angle of the vehicle is detected by integrating the yaw rate simultaneously with the start of the lateral movement, and in order to return the vehicle attitude of the vehicle to its original state by converging the yaw angle to 0 in the final stage of the lateral movement, a yaw angle correction control current is superimposed on the lateral movement control current and supplied to the actuator. By using the current supplied to the actuator (that is, the steering torque generated by the actuator) as the steering target value for avoiding a collision instead of the steering angle, the actuator can be prevented from generating excess steering torque which gives an uncomfortable feeling to a driver.

摘要： A system for controlling safety running of a vehicle, including obstacle detecting means such as a laser radar for detecting an obstacle (e.g., other vehicle) present ahead on a course of travel of the vehicle, and operating means for operating a braking system of the vehicle to avoid contact with the obstacle. In the system, if it is found that the obstacle detected by the obstacle detecting means is lost, the operating means operates the braking system based on at least an estimated possibility of contact or degree of certainty of obstacle. With the arrangement, the system can appropriately cope with a situation in which an obstacle, once detected, is lost during braking operation, without degrading the driving feeling or comfort and without causing the vehicle driver to experience annoyance, while ensuring obstacle avoidance without fail.

摘要： A method and apparatus for managing access to a resource using anticipatory lock conversions in a distributed lock management system is provided. According to the method, when an entity requests a lock on a resource, the entity is granted, if possible, a lock with a more restrictive lock mode than is required if it is determined that the entity may require the more restrictive lock mode in the near future.

摘要： Synchronization services provide a concurrency-safe reader/writer lock supporting a time out feature. The lock can be implemented using lockless data structures to provide efficient synchronization services. Various features such as lock nesting and auto-transformation address common scenarios arising in componentized programs. The lock supports upgrading and suspension, and the time out feature can support an efficient, low-cost optimistic deadlock avoidance scheme. Peculiarities of the reader/writer scenario are addressed in an efficient way to maintain lock stability and consistency, thus providing synchronization services suitable for implementation at the kernel level. In one implementation using event objects, the events are managed for high efficiency and stability of the lock. For multiprocessor machines, a hybrid lock avoids a context switch by behaving as a spin lock before waiting for the lock to become available.
