A driving/braking force manipulation control input of a k-th wheel, which denotes one or more specific wheels among a plurality of wheels of a vehicle, is determined such that a required condition concerning a relationship among a road surface reaction force that may act from a road surface on the k-th wheel on the basis of the detected values or estimated values of a side slip angle and a friction characteristic of the k-th wheel, a feedback control input related to the driving/braking force of the k-th wheel for bringing a difference between a state amount of the vehicle and a reference state amount close to zero, a driving/braking force feedforward control input based on a drive manipulated variable supplied by a driver of the vehicle, and a k-th wheel driving/braking force manipulation control input is satisfied. This arrangement makes it possible to properly control a motion of an actual vehicle to a desired motion while properly considering the characteristics of a road surface reaction force acting from a road surface on a wheel.

Vehicle Control Device

A lock bolt (14) extendible and retractable by movement of a power transmission assembly (20) driven by an actuator (18) and having a cam (32) thereon which cams against the lock bolt (14) to retract the lock bolt and unlock the steering column. The cam (32) has a curved surface (40) with varying distance from the axis of rotation of the cam (32) or pivot to improved lock bolt motion. The cam (32) can have a gradual ramp surface (40) to extract a lock bolt (14) even in binding conditions of the lock bolt. In some embodiments, one or more sensors (56, 58) directly or indirectly connected to the actuator (18) can be used to trigger deactivation of the actuator (18) when the lock bolt (14) has been or can be sufficiently moved to its locked and unlocked positions.

Steering column lock apparatus and method

An immobilizer ECU (6) transmits a vehicle ID code (VID-A) and a SEED code (SC-2h), which is read from an electronic key (2b), to a data center (10) online. The data center (10) generates an encryption key (K-2 from the received SEED code (SC-2h) and a first logic (h), and generates a further SEED code (SC-2Ag) from the encryption key (K-2), the vehicle ID code (VID-A), and a second logic (g). The immobilizer ECU (6) obtains the further SEED code (SC-2Ag) online from the data center (10), generates the encryption key (K-2) from the obtained further SEED code (SC-2Ag), the vehicle ID code (VID-A), and the second logic (g), and stores the encryption key (K-2).

Electronic key registration system

The invention relates to a device for blocking a motor vehicle steering shaft (1) and preventing the rotation thereof by means of a blocking bolt (2) interacting with the blocking slots (3) of the steering shaft (1). A blocking pin carries out a reciprocating motion between the blocking position and a releasing position thereof by means of a control element (15) which is rotated in two directions by an electric motor (13) and interacts with a rotating position sensor (17). The aim of said invention is to develop a device as compact as possible. For this purpose, the control element is embodied in the form of a circular control disk (14) whose face (15) interacts with the blocking bolt (2) and the other face thereof (16) interacts with the rotating position sensor (17).

Blocking device for a motor vehicle steering shaft

A vehicle system includes one or more vehicle processors programmed to: provide a user interface to program a first wireless device as a new vehicle key and to delete a second wireless device as an existing vehicle key. The one or more vehicle processors may be further programmed to wirelessly transmit vehicle key security codes from the vehicle to the first device to program the first device. The one or more vehicle processors may be further programmed to display one or more programmed devices including the second device via a user interface for user selection to delete the second device as an existing vehicle key.

A highly reliable steering lock device (1), comprising a lock pin (21) engaged with a steering (5), a motor (23) for operating the lock pin, and a control circuit (31) for controlling the motor, the control circuit further comprising a power supply path (72b) for feeding a lock current for locking the steering to the motor, wherein, when a user operates an ignition switch knob (81) to start a vehicle, a cutout circuit (61) selectively cuts out the power supply path.

Electronic vehicle theft preventive device

This electronic-key registration method, in which a plurality of electronic keys (2) including an initially registered first electronic key and a second electronic key to be registered additionally are registered with a control device (6) for a communication target, is provided with the following steps: an additional-key manufacturing step in which an additional-encryption-key generation code (SC-9) unique to the second electronic key and an additional encryption key (K-9) used in authentication of the second electronic key are stored in the second electronic key; and an additional-key registration step in which, if identifying information (VID-A) unique to the communication target is stored in the second electronic key, the additional-encryption-key generation code (SC-9) is obtained from the second electronic key, an additional encryption key (K-9) is generated by additional-encryption-key generation logic (g) using the additional-encryption-key generation code (SC-9) and the aforementioned identifying information (VID-A), and said additional encryption key is stored in the control device (6).

An electronic automobile anti-theft apparatus having high reliability includes a motor, which moves a lock pin to lock a steering shaft of an automobile A solenoid maintains the lock pin in a state released from the steering shaft and operates to permit the lock pin to lock the steering shaft by receiving power An ECU controls the operations of the motor and the solenoid A mechanical switch stops supplying the solenoid with power to prevent unintentional locking by the lock pin when the automobile is being driven or when driving of the automobile is enabled

Electronic automobile anti-theft apparatus

A start control apparatus has a steering lock mechanism, which includes a lock pin and a lock control unit. The lock pin is selectively engaged and disengaged from the steering shaft. The lock control unit controls the lock pin. The start control apparatus further includes a portable communication device, a verification control unit, which communicates with the portable communication device, a power source control unit, which control power supply, an engine control unit, which controls the engine, a lock state detecting switch, which detects an engaged state and a disengaged state of the lock pin. The lock control unit and the power source control unit monitor detection signals from the lock state detecting switch. The engine is permitted to be started on condition that the control units acknowledge that the lock bar is in the disengaged state.
