Abstract
Description
Claims (8)
- It is 1. a kind of suitable for driver attention's monitoring of uneven road surface and caution system, which is characterized in that including acquisition of information Module, electronic control unit module, alarm module, described information acquisition module are connected with electronic control unit module, the electricity Sub-control unit module is connected with alarm module;Described information acquisition module is the torque sensor on steering column and vehicle speed sensor and measures deflecting roller The sensor of upper aligning torque, the torque sensor are used to obtain the torque on steering column, and the vehicle speed sensor is used for Obtain real-time speed;The electronic control unit module is increased for the electronic control unit of wire-controlled steering system for comparing on deflecting roller Aligning torque with set first threshold and compared with steering wheel torque with setting second threshold judgment module, to alarm mould Block sends out the electronic control unit module of alarm command, prejudges the program of driver's correct operation, wherein the steering-by-wire system System is made of two controllers, is steering controller and road feel controller respectively, is passed between two controllers by Flexray buses Pass information;The first threshold has reached for aligning torque to be needed pilot control steering mechanism and ensures to go to change travel direction Cross the value of Cheng Pingshun;The second threshold is minimum torque values caused by driver's active manipulation direction disk, and second threshold is simultaneously It is not definite value, driver sets according to the situation of itself.
- 2. it is according to claim 1 a kind of suitable for driver attention's monitoring of uneven road surface and caution system, it is special Sign is, when the aligning torque on deflecting roller reaches first threshold, compares the steering wheel torque and that torque sensor is measured Whether manipulation direction disk is turned to two threshold decision drivers, if the torque value that torque sensor measures is less than second threshold, Then illustrate that driver does not concentrate one's energy to drive at this time, electronic control unit module sends out alarm command to alarm module, reminds Pilot control wheel steering;If the torque value measured is higher than second threshold, sentenced according to aligning torque at this time and speed Whether the steering operation that disconnected driver applies on the steering wheel is correct, if correctly, terminating this wheel work, if incorrect, sending out Go out alarm command and remind driver's operating mistake, compared to the electric boosting steering system of mechanical connection, wire-controlled steering system turns Influence torque sensor measurement direction disk torque on steering column is not transferred to wheel aligning torque, is more convenient for accurately judging Driver, which unclamps, still holds steering wheel.
- 3. it is according to claim 1 a kind of suitable for driver attention's monitoring of uneven road surface and caution system, it is special Sign is that, when the torque that steering wheel torque sensor measures is less than second threshold, explanation is that driver's hand is put on the steering wheel When unconscious rotation, dtc signal is amplified at this time and it is monitored, if torque becomes zero from a certain moment and continues Be zero be more than certain time, then illustrate driver may both hands departure direction disks, electronic control unit module is to alarm mould at this time Block makes a sound alarm command and reminds driver.
- 4. it is according to claim 1 a kind of suitable for driver attention's monitoring of uneven road surface and caution system, it is special Sign is, when judging that driver attention does not concentrate or when steering operation mistake starts audible alarm and steering wheel vibration simultaneously Alarm.
- 5. it is according to claim 4 a kind of suitable for driver attention's monitoring of uneven road surface and caution system, it is special Sign is, does not collect the prompting for neutralizing driver's operating mistake respectively as driver attention with two different form of vibration, The vibration mode that specially prompting driver attention does not concentrate is continuous shaking, prompts the vibration mode of driver's operating mistake It was a cycle cycling cycling vibration for 0.2 second with continuous shaking stopping vibration in 0.5 second.
- 6. it is according to claim 4 a kind of suitable for driver attention's monitoring of uneven road surface and caution system, it is special Sign is, can set a frequency oneself liked after the vibration for experiencing each frequency by driver.
- 7. it is according to claim 1 a kind of suitable for driver attention's monitoring of uneven road surface and caution system, in vehicle Speed works when being more than 30km/h.
- 8. it is according to claim 1 a kind of suitable for driver attention's monitoring of uneven road surface and caution system, it is special Sign is, includes the following steps:Monitor the aligning torque and steering wheel torque on deflecting roller, and the deflecting roller aligning torque and steering wheel torque that will be detected Input to electronic control unit module;The aligning torque and first threshold on deflecting roller that electronic control unit relatively monitors; Electronic control unit module compares steering wheel torque and second threshold simultaneously;If judging result is reached for the aligning torque on deflecting roller To first threshold, the steering wheel torque measured is more than second threshold i.e. driver's active manipulation direction disk and operating mistake then electronics Control unit sends out alarm command and sends out business and control road feel simulated machine that steering wheel vibration is driven to be reminded as warning message Driver;List is controlled electronically if judging that steering wheel torque also reaches preset limiting value less than second threshold and duration Element module control voice device sends out alarm voice, this wheel work terminates;If judging result is returns positive force on deflecting roller Square does not reach first threshold, this wheel work terminates, and starts next round monitoring;If judging result is not below for steering wheel torque Second threshold or be still consistently less than less than second threshold the limiting value time do not reach preset limiting value then this wheel monitoring knot Beam starts next round monitoring.
