What are the disadvantages of ACC adaptive cruise control?

ACC adaptive cruise control has the following disadvantages: risk control. The basic function of adaptive cruise control is to maintain the vehicle's longitudinal movement. When there is a collision risk, the vehicle will alert the driver and perform active braking intervention. However, actual road conditions are constantly changing, and the system cannot 100% avoid all risk scenarios, which may cause the driver to lower their vigilance. Having the foot away from the pedal position will increase reaction time. Adaptive cruise control can also be referred to as active cruise control, similar to traditional cruise control. The system includes radar sensors, digital signal processors, and control modules. In the adaptive cruise control system, the system uses low-power radar or infrared beams to determine the exact position of the vehicle ahead. If it detects that the leading vehicle is slowing down or identifies a new target, the system sends execution signals to the engine or braking system to reduce speed, thereby maintaining a safe distance between the vehicle and the one ahead. When the road obstacle ahead is cleared, the system will accelerate to restore the set speed, and the radar system will automatically monitor the next target.

Why is the steering wheel stiff and heavy?

The reasons for a heavy steering wheel include insufficient power steering fluid, low tire pressure, and overly tight bearing fit. Below is a detailed explanation of the solutions for a stiff steering wheel: 1. Insufficient power steering fluid: Normally, the steering effort feels relatively consistent. If it suddenly becomes heavy one day or gradually increases in resistance, it may be due to dirty power steering fluid, similar to engine oil, which needs replacement. Alternatively, a fluid leak reducing the fluid level can decrease power assistance, making the steering wheel heavy. This situation requires timely maintenance or replenishment/replacement of the power steering fluid. 2. Low tire pressure: Low tire pressure increases the contact area between the tire and the road surface, raising friction and making steering more difficult, resulting in a heavy steering wheel. This is unsafe for driving and requires immediate tire pressure replenishment. 3. Overly tight bearing fit: For the rolling bearings in the steering system, if they fit too tightly with sliding bearings, it can hinder proper lubrication, leading to sticking issues and a heavy steering wheel. In this case, inspect the mechanical parts and power steering system, or check for possible leaks or damaged intake seals.

What is the handling method for a 12-point violation on the highway?

If the driver's license is Class C, a one-time deduction of 12 points requires retaking the subject one exam. After passing the exam, the driver's license can be reinstated. For Class A or B licenses, the penalties are more severe, involving not only the exam but also a downgrade. Below are detailed introductions about driver's licenses: 1. Classification: The Ministry of Public Security officially issued the "Regulations on the Operation of Motor Vehicle Driver's License Services," implementing a graded system for motor vehicle driver's licenses, dividing them into 15 classes: A1, A2, A3, B1, B2, C1, C2, C3, C4, D, E, F, M, N, and P. 2. Renewal Regulations: If a motor vehicle driver does not accumulate 12 points in any scoring period during the six-year validity of the driver's license, it can be renewed to a ten-year validity license. If no 12 points are accumulated in any scoring period during the ten-year validity, it can be renewed to a long-term valid driver's license.

How to Activate Cruise Control on the 10th Generation Accord?

Turn on the cruise control switch labeled CRUISE, and the cruise control indicator light on the dashboard will illuminate. Accelerate to your desired speed, then press the SET button to lock in the current speed. Once set, you can remove your foot from the accelerator pedal. To adjust the speed, press RES+ to increase or SET- to decrease. Cruise control can be deactivated by pressing the brake pedal, pressing the CANCEL button, or toggling the ON/OFF switch. To resume the previously set speed after deactivation, press the RES button. Below are the steps to activate cruise control: 1. Press the CRUISE button located at the top right of the steering wheel; this is the master switch for cruise control. You will see a green CRUISE-MAIN indicator light on the dashboard, signaling that the cruise control system is in standby mode. 2. Accelerate to your desired speed, then press the DECEL-SET button to engage cruise control without needing to press the accelerator. 3. To disengage cruise control during operation, press the brake pedal or the CANCEL button. 4. During cruise control, pressing or holding RES will increase speed. Alternatively, you can press the accelerator to reach a higher speed and then press RES to set the new speed. 5. Pressing or holding SET during cruise control will decrease speed.

What light comes on when brake fluid is low?

The handbrake warning light will illuminate when the brake fluid is low. This is because there is a fluid level sensor inside the brake fluid reservoir that monitors the amount of brake fluid. If the brake fluid level drops below the position of this sensor, it indicates a decrease in brake fluid, alerting the driver to inspect the brake system. Brake fluid levels can decrease due to thinning brake pads. Typically, brake pads have a service life of about 80,000 kilometers. Frequent use of the vehicle and frequent braking naturally increase the number of times the brake pads are subjected to friction, leading to faster wear. Conversely, less frequent use of the vehicle and a driving style that relies more on engine braking before applying the brakes will result in much slower brake pad wear. As brake pads wear down over time, the pistons inside the brake calipers gradually extend outward to compensate for the gap created by the worn pads. These pistons are pushed by the pressure generated by the brake fluid when the brakes are applied. The adjustment of the pistons to fill the gap increases the internal space of the brake calipers, which is then filled by the brake fluid. This ultimately causes the brake fluid level in the reservoir to appear significantly lower.

What to Do If the Time for Driver's License Renewal Has Expired?

If the time for driver's license renewal has exceeded but not yet one year, hurry to renew it. The relevant regulations are as follows: 1. As long as it does not exceed one year, the annual review can be conducted normally. According to the "Regulations on the Application and Use of Driver's Licenses" (Order No. 111 of the Ministry of Public Security), it is clearly stipulated: "The motor vehicle driver shall apply for renewal at the vehicle management office of the place where the motor vehicle driver's license was issued within 90 days before the expiration of the motor vehicle driver's license. The annual review will not be canceled if the driver's license expires within one year. 2. The annual review can be conducted within one year without being fined. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" by the Ministry of Public Security, Chapter 5, Article 67, Paragraph 7, if the renewal of the motor vehicle driver's license exceeds one year after the expiration, the vehicle management office shall cancel the motor vehicle driver's license. 3. To renew the driver's license, you need to bring your ID card, driver's license, four one-inch white background color photos, and a medical examination form to the local vehicle management office for processing.
