Patent number: 8832704Abstract: An in-car-use multi-application execution device is provided that ensures safety while maintaining convenience by securing operation of a plurality of applications and suppressing occurrence of a termination process within a limited processing capacity without degrading a real-time feature. The in-car-use multi-application execution device dynamically predicts a processing time for each application, and schedules each application on the basis of the predicted processing time. If it is determined that an application failing to complete a process in a prescribed cycle exists as a result of the scheduling, a process is executed that terminates the application or degrades the function of the application on the basis of a preset priority order.Type: GrantFiled: August 12, 2010Date of Patent: September 9, 2014Assignee: Hitachi Automotive Systems, Ltd.Inventors: Masayuki Takemura, Shoji Muramatsu, Isao Furusawa, Shinya Ohtsuji, Takeshi Shima
