  • Patent number: 7894988
    Abstract: A vehicle driving assist system has a host vehicle risk factor detection section, a peripheral risk factor detection section, a host vehicle risk potential calculation section, a peripheral risk potential calculation section and a risk potential notification section. The host vehicle risk factor detection section detects host vehicle risk factors related to a host vehicle. The peripheral risk factor detection section detects peripheral risk factors in an area around the host vehicle. The host vehicle risk potential calculation section calculates a host vehicle risk potential attributed to the host vehicle risk factors. The peripheral risk potential calculation section calculates a peripheral risk potential attributed to the peripheral risk factors. The risk potential notification section notifies a driver of the host vehicle risk potential and the peripheral risk potential using a common risk notification device for both notifications.

  • Publication number: 20100179719
    Abstract: A vehicle driving assist system calculates a risk potential indicative of a degree of convergence between a host vehicle and a preceding obstacle. Then, the system performs a driver notification operation that produces a driver notification stimulus based on the risk potential such as decreasing the driving force exerted against the vehicle as the risk potential increases and increasing an actuation reaction force exerted on the accelerator pedal during its operation as the risk potential increases. If a failure is detected in a reaction force generating device serving to add a reaction force to the accelerator pedal in accordance with the risk potential, then the system corrects an engine torque characteristic such that the engine torque does not increase even if the accelerator pedal is depressed to suppress an odd feeling in the vehicle performance by the driver when a failure occurs in the reaction force generating device.

  • Patent number: 7739022
    Abstract: A vehicle driving assist system is provided that increases an actuation reaction force exerted by the accelerator pedal, when it is operated, as a risk potential with respect to a preceding obstacle increases. The system also lowers the driving force and increases the braking force exerted against the host vehicle as the risk potential increases. During braking/driving force control based on the risk potential, the system changes a braking/driving force control operating schedule in accordance with the driver's intentions with respect to accelerate or decelerate.

  • Publication number: 20090164082
    Abstract: An inter-vehicle distance maintenance supporting system may include an operational reactive force generating device that generates an operational reactive force on a driving operational equipment based on a first inter-vehicle distance threshold. A driving operational equipment state detector detects an operational state of the driving operational equipment and acceleration intent of the driver. An engine controller controls an engine torque corresponding to the operational state of the driving operational equipment. An engine torque correcting device decreases the engine torque before the operational reactive force is generated. The decrease correction is suppressed when the inter-vehicle distance is greater than a second inter-vehicle distance threshold that is larger than the first inter-vehicle distance, and the driving operational equipment state detector detects the acceleration intent of the driver.

  • Publication number: 20080123718
    Abstract: A positioning apparatus is provided that reduces the time required to acquire spreading codes of satellite signals. In a positioning apparatus (100) having a plurality of channels CH1, CH2, . . . , a spreading code generator (104) provided for each channel generates a spreading code of a GPS satellite which is set by a control section (107). A spreading code phase control section (109) sets the initial phases of spreading codes set on the channels, respectively, such that the initial phases are sifted between the channels CH1 and CH2. When one channel (e.g., CH1) succeeds in acquiring a spreading code, the initial phase of the spreading code of another channel (CH2) is reset based on a spreading code phase of the one channel.
